    ABSTRACT: For the study of MSW landfills in which the lining system is composed of a compacted clay liner (CCL), a two-layer strata model is presented to reproduce the system which consists of a CCL and an underlying aquifer. Considering all types of mechanisms including advection, hydrodynamic dispersion and sorption of soil skeleton, one-dimensional differential equation is formulated for describing the migration behaviour of contaminant in the CCL and aquifer. Together with the actual initial and boundary conditions, the resulting initial boundary value issue is numerically solved by various effective procedures. Based on abundant numerical computations by varying various relevant parameters, the effects of the production modes of contaminant source, hydraulic conductivity and dispersion as well as various sorption behaviours of the CCL, the equilibrium and linear sorption of the aquifer as well as biochemical degradation on the migration behaviour of contaminants in both the CCL and aquifer are systematically examined. It is shown that an independent mechanism in addition to hydrodynamic dispersion and advection, the sorption of soil skeleton plays a much important role in controlling the migration behaviour of contaminants. The sorption model and its parameters should be carefully chosen in the numerical analysis of contaminants migration and design of MSW landfill. Moreover, both coefficients of hydraulic conductivity and dispersion of the CCL should be duly determined according to the actual condition. Compared with the sorption effect of the CCL, the influence of sorption of aquifer on the migration behaviour of contaminants can be overlooked.

    ABSTRACT: The effects of soil–tunnel structure interaction are proved to be quite significant, particularly under earthquake excitation. The influence of earthquakes on a tunnel–ground interaction depends on the peak acceleration, the intensity and duration of the earthquake, and outmost on the relative rigidity between the tunnel and the ground. With an aim to study the effects of tunnel–ground interaction, two-dimensional simplified dynamic linear analyses have been undertaken using the finite element based commercial software ANSYS. The present study employs a continuous FE model in order to estimate the soil–structure interaction effects regarding tunnel structures under earthquake action, for the cases of both good and poor soil conditions. The earthquake loading is simulated under simple shear conditions obtained by means of a one-dimensional free-field site response analysis in the code EERA. The obtained numerical results are compared to the most frequently used analytical expressions, and by that, a capability of the models to simulate the most important aspects of the SSI effects is validated. Furthermore, a comparison of the results for the cases of dense and loose soil conditions is performed, and their reliability, considerable mutual differences, as well as significant factors influencing tunnel–ground interaction for both cases, are evaluated.

    ABSTRACT: Energy conservation and environmental protection has progressively developed into the hot and popular topics in nowadays. In the process of natural gas transmission, almost all the power of the compressor stations has been used to overcome the friction consumption between the flowing gas and pipeline wall, so large numbers of resources are spent on the maintenance of the pumping stations every year. How to reduce the wall friction and increase the transportation output has been becoming the urgent problem to be resolved. Internal smooth coating, injecting nano-chain drag reduction agent and bio-inspired drag-reducing morphology have been gradually taken into application in the past several decades, and the field testing results were all striking and satisfactory. An overview of applying different drag reduction technologies into nature gas pipelining is systemically presented in detail, which has the important significance to understand research status and development tendency of nature gas industry.

    ABSTRACT: Massive reinforced concrete (RC) structure is widely used in long-term damp environments. To improve the concrete durability and reduce the reinforcing steel corrosion, crack width control is more rigorous in massive RC structure. In this paper, the short-term (30 days) temperatures of concrete are measured by the distributed temperature system (DTS) to inverse the thermal parameters using the genetic algorithm (GA), and the long-term (300 days) temperature is predicted by using the calculated thermal parameters. Moreover, thermal stress field considering the creep is calculated based on the eight-parameters-equation, and the parameters were modified by the results of temperature stress test machine (TSTM). Furthermore, a quantitative reinforcement configuration method is proposed on the basis of the predicted thermal stress field, and its feasibility and effectiveness are verified by a sluice pier structure. Finally, the optimal reinforcement scheme obtained was selected by the comparisons of the crack width, reinforcement stress and the total cross-sectional area of reinforcement. This article provides a new methodology to design reinforcement configuration for massive RC structure.

    ABSTRACT: Concrete is one of the most widely used construction and building materials. When a concrete structure reaches the end of its life, the demolition waste may be used to produce recycled concrete aggregates (RCA). RCA mainly differ from natural aggregates in the attached mortar that remains onto the RCA surface. The differences between the properties of RCA and those of natural aggregates will condition the performance of the construction materials that contain RCA. Specifically, asphalt concrete (AC) that contains RCA has many technical disadvantages due to the porous nature of the attached mortar and thus, the high water and bitumen absorption and the low resistance to fragmentation of the RCA. However, some authors have experimented with the application of treatments to the RCA that allow its successful use in the manufacture of AC, which contributes to sustainable development. This paper reviews the main properties of the RCA, particularly when used to produce AC.

    ABSTRACT: In the case of bridge structures the ability to determine the life of a damaged bridge span as a function of load cycles is fairly essential. It allows the person who is responsible for the service of such a structure to make decisions related to the necessity of its possible repair. One of the basic parameters used in the analysis of service lifecycle of steel structures with a damage of a particular size, is the stress intensity factor K, which is used in a large number of formulas describing the growth rate of fatigue cracks. The work presents an assessment of a possible use of the finite elements method to calculate using the stress intensity factor K directly. The obtained results were compared with the results obtained with three other methods based on the FRANC2D software and with laboratory own tests results. Taking into account the results of these analyses presented in the paper it was found out that the FRANC2D software is a very useful and practical tool in strictly engineering tasks.

    ABSTRACT: Pressure indicated by earth pressure cell (EPC) often deviates from field earth pressure . EPC in normally consolidated soil was analysed with Taylor’s indentation method. It is found that assumes a linear relationship with soil’s compression modulus and . When preconsolidation pressure imposed on overconsolidated soil is unloaded, soil’s rebound strain is greater than EPC’s, and a gap between EPC’s sensing plate and soil appears. Upon reloading, contact between sensing plate and soil resembles spherical contact. This contact was analysed with Hertz’s solution and it is found that is in direct ratio with , and is less than for a relatively low earth pressure and is greater than for a relatively high earth pressure. Earth pressure measurement experiments were conducted with river sand. Experimental results conform to the theoretical analysis herein for a relatively low earth pressure made in this paper.

    ABSTRACT: Shear strain in soil is one of the most important factors controlling the response of soil layers under earthquake. Therefore, recognition of changes in soil behaviour under different strain amplitudes is necessary. Based on the published experimental data, alternative cyclic strain regime divisions are proposed. The cyclic strain thresholds that represent the change in cyclic behaviour and properties of soil are used to divide these different cyclic strain regimes. The criteria taken into account to obtain these regimes include stress–strain behaviour, pore-water pressure generation, volume change, stiffness degradation, post-cyclic strength and micro-scale processes. In this study, the cyclic threshold shear strains for pore-water pressure generation, stiffness degradation and post-cyclic strength are investigated in very dense clean sand. It is specified that the cyclic threshold shear strain for pore-water pressure generation in very dense sand is higher compared to those relating to loose and relatively dense sand which is referred to in the literature. Moreover, two methods referred to in the literature are compared to calculate the threshold strain of stiffness degradation. Also, it was determined that when pre-cyclic shearing is more than a specified amplitude, the positive effect of pre-loading due to increasing relative density and the shear strain history can be eliminated or even can be inverted.

    ABSTRACT: To get a better understanding of the effect of drying/wetting cycles on the mechanical cyclic behaviours of silty clay, cyclic triaxial tests were performed on slurry consolidated silty clay specimens with various numbers of drying/wetting cycles, matric suctions, cyclic shear stresses and loading frequencies. Additionally, the soil microstructure before and after drying/wetting cycles was investigated with scanning electron microscope. The laboratory test results indicate that the threshold cyclic stress ratio and cyclic shear strength increased significantly at low matric suction due to drying/wetting cycles, with the changes becoming more gradual as matric suction continues to increase. The variation of mechanical cyclic behaviours is attributed to the irreversible compression, development of micro-cracks and lower degree of saturation. The overall influence of drying/wetting cycles depends on the weights of the three factors. For the specimens subjected to drying/wetting cycles, the cyclic shear strength increased with the increasing of loading frequency. Scanning electron micrographs show that soil particles were drawn closer together during the drying/wetting cycle process which led to variation of microstructure, resulting in alteration of the mechanical behaviours. The variation of the mechanical behaviours is consistent with the reconstruction of the soil microstructure.

    ABSTRACT: This paper presents the results of an experimental investigation into the hardened density of freshly compressed concrete and its effect on the mechanical properties including compressive strength and modulus of elasticity. The concrete specimens were compressed in a fabricated pressure apparatus under different values of pressure and reference concrete strength. Two types of pressure, long-term pressure and short-term pressure were also applied to the fresh concrete to evaluate the effect of pressure duration on the concrete density. The results indicated that the increase in the compressed concrete density increases with the increase in primary pressure and decrease in reference concrete strength. Moreover, the pressure duration poorly affects the concrete density. By considering the density, this study also provides a model for predicting the modulus of elasticity of the compressed and the uncompressed concretes, which covers the wide range of the compressive strength between 18 and 81 MPa. Finally, a comparison between the measured values of the modulus of elasticity and those calculated by the prediction models, given in ACI 318, ACI 363 and EC2, was performed, and then correction factors were proposed for the model codes to estimate the modulus of elasticity of the compressed concrete. The results showed that ACI 318 and ACI 363 models involving the concrete density yield correction factors close to one, while EC2 model involving a coefficient reflecting the effect of aggregate type gives a very higher value.

    ABSTRACT: The paper focuses on the propagation of debonding along an interface between a concrete substrate and a cement-based thin-bonded overlay under fatigue loading. The investigated overlay materials were fibre reinforced and rubberised cement-based mortars. Tensile tests were performed to obtain the residual normal stress–crack opening relationship for the overlay materials. The drying shrinkage of the overlay materials was characterised by tests on prismatic specimens that showed the evolution of drying shrinkage vs. the mass loss. The substrate–overlay interface was investigated by static tensile tests to provide the relationship between debonding opening and residual normal tensile stress. Its evolution under fatigue loading was assumed to follow a cyclic bridging law for plain concrete. Three-point bending fatigue tests were then carried out on repaired substrate to obtain information on the structural behaviour of the interface. The debonding propagation was monitored by a video microscope with a magnification of 175×. Relying on the identified and quantified parameters, the above-mentioned fatigue tests were modelled by the finite element method using the CAST3M code developed in France by Atomic Energy Commission. A comparison between model and experimental results shows good agreement and proves the important role of fibre reinforcement and of rubber aggregates on the durability of the repair with respect to debonding.

    ABSTRACT: The equipment of French nuclear power plants is fixed on reinforced concrete structures with base plate with headed fasteners. Electricity of France decided to carry out an experimental research program in partnership with Laboratory of Civil and Environmental Engineering in order to optimise the design of the headed fasteners and identify safety margins. This article introduces the results of static tension tests on an anchorage composed of an anchor plate welded to four headed rods. The anchors are cast in place in a reinforced concrete block. The experimental campaign is carried out on anchors and anchor groups with reduced embedment depths. Tests on single headed rods are also carried out in order to analyse the group effects. The sliding of the anchor groups, the strain of the head rods, the strain of the stirrups and the surface concrete block displacements are measured. The collapse of the anchorages is caused by a failure of the steel rods or a concrete breakout failure for a loading ranging between 600 and 300 kN. The experimental ultimate strength is compared with ultimate load obtained from the technical specifications of Eurocode. This experimental campaign will provide a data base enabling the development of numerical models in order to improve the design.

    ABSTRACT: Tensegrity systems are self-stressed reticulate structures, composed of a set of compressed struts assembled inside a continuum of tendons. This principle can be at the origin of large, lightweight and transparent structures. In practice, a few structures of this kind were built, partly because they are very demanding in design and analysis. In the wish to contribute to the development of practical structural applications, we propose in this paper a design procedure that combines form-finding and structural dimensioning under static load. To optimise the behaviour in the dynamic domain, we present a general methodology suited for the control of the first vibration modes. The case of a modular tensegrity footbridge is taken for application, taking into account different materials.

    ABSTRACT: Ore and mineral extraction by underground mining often causes ground subsidence phenomena, and may induce severe damage to buildings. Analytical methods based on the Timoshenko beam theory is widely used to assess building damage in subsidence regions. These methods are used to develop abacus that allow the damage assessment in relation to the ground curvature and the horizontal ground strain transmitted to the building. These abacuses are actually developed for building with equivalent length and height and they suppose that buildings can be modelled by a beam with isotropic properties while many authors suggest that anisotropic properties should be more representative. This paper gives an extension of analytical methods to transversely anisotropic beams. Results are first validated with finite elements methods models. Then 72 abacuses are developed for a large set of geometries and mechanical properties.

    ABSTRACT: This article shows experimental investigation carried out to study the effect of exposure to elevated temperature on concrete. Four concrete mixes obtained using different proportions of ground granulated blast furnace slag (GGBFS) and silica fume (SF) with 43 grade ordinary Portland cement were considered. Concrete cubes of 100 mm size were cast, cured and exposed to different peak temperatures (up to 700 °C) for different heating periods (1, 2, 3 and 7 h) and tested to failure under compression. Before subjecting the heated specimens to compression test, the heated cubes were closely examined for any signs of cracking, disintegration and loss of mass. The concrete specimens with 5% SF do not show any sign of cracks at different peak temperatures, whereas 10% SF cubes split from corners at 425 °C. However, the concrete cubes with 10% GGBFS did not show any sign of cracking even for 7-h exposure to a temperature of up to 500 °C. The mass loss of all concrete specimens increased sharply up to 200 °C, and after that, it increased marginally. The compressive strength of all concrete mixes increased up to 200 °C and decreased with further increase in temperature, with the exception of concrete containing 5% SF which increased even at higher temperatures but at a slower rate.

    ABSTRACT: The paper intends to study the seismic performance of the frame-supported multi-ribbed composite wall (FSMRC wall) with large space at the bottom and with that purpose, it conducts low-reversed cyclic loading experiment to two such specimens, with their scales reduced by 1/2 of the prototypes. Afterwards, the paper looks into the major parameters - failure process, the hysteresis of the vertex-horizontal displacement and of inter-storey displacement, the skeleton curves and the loading-strain curves of the members’ reinforcing steels - of the specimens, both with and without holes, and then carries out comparative studies on the results. On this basis, the stiffness degradation and the residual deformation ratio are discussed, and the experiment results stand as the following: the structure as a whole delivers an extraordinary seismic performance, thanks to the unique layer-by-layer embedded upper design. It should be noted that the failure process and the stiffness degradation of both specimens, with and without the holes, are found to be roughly consistent; at the same time, both has proven to be fairly good in terms of displacement ductility, collapse resistance and repairability.

Focus is then made on effective diffusive properties prediction through numerical homogenisation, using the Lattice Boltzmann method, exploring the stability limits and performance of this method for heterogeneous media. Une méthode originale de création de morphologies de pâtes de ciment en cours d’hydratation à l’aide d’excursions de champs aléatoires corrélés est introduite. On présente ensuite le calcul des propriétés diffusives effectives homogénéisées de ces pâtes à l’aide de la Méthode de Boltzmann sur gaz réseau, les limites de stabilité et de performances associées à cette méthode pour les matériaux hétérogènes, ainsi qu’une application aux pâtes de ciment en cours d’hydratation.

    ABSTRACT: The measurement framework allowing for analyses on standard products, such as dense hot-mix asphalt, must be completed to analyse the behaviour of porous cold-mix asphalts. Such soft materials need time to stabilise its performances and short-term loading can drive to large deterioration of the applied layer. The effects of wheel tread turning and rubbing on asphalt surface have to be understood. In order to do that, the tribological behaviour of an asphalt surface is studied using an apparatus that can load a sample surface simultaneously in compression and torsion. The paper describes the technical details and the design of the apparatus, followed by a description of the adopted experimental test protocol. Tests are realised with imposed normal load and rotation rate of a disc. The adhesion and friction stresses are calculated from torque measurement. The displacement of sample surface during torsion is recorded. The value of this parameter at the end of the test appears as a useful degradation indicator. Performing tests during ageing of sample enlighten us on the stabilisation of the performances. The interpretation of results is illustrated by tests carried out on porous cold-mix asphalt that is particularly sensitive.
