In timber-concrete composites (TCC), more researchers are trying to find the "ultimate" shear connector, which combines multiple advantages. Bonded steel plates are one of the possible solutions. This paper provides an analytical and a numerical approach, calibrated with previously conducted experiments, to predict the load carrying capacity, and c...
This work aims to characterise the behaviour of structural adhesives for timber-glass connections by performing experimental tests and calibrating numerical models. An adhesive bond between timber and glass can solve two conflicting requirements in timber frame structures.: (i) horizontal stability provided by shear walls/vertical diaphragms; (ii)...
Hybrid testing provides an efficient and less costly way to explore the response of structural systems to realistic dynamic or seismic loading. However, the required equipment to execute hybrid tests are high-cost tools. To get insight in the hybrid testing methodology, a small-scale set-up has been developed in this project.
An Arduino UNO control...
To evaluate the behaviour of a single timber-concrete composite (TCC) T-beam, a simplified 2D finite element (FE) model in Abaqus is developed and validated using experimental tests and the Gamma method given in Annex B of EN 1995-1-1. The shear connection used in the beam consist of perfobond connectors, which are adhesively bonded to the timber b...
The exponential growth of e‐commerce in the last decade boosts the need of large logistic centers. Steel rack supported warehouses (SRSWs) are one of the most competitive solutions for such infrastructures. The execution phase of SRSWs is challenging, as the stability of the structure has to be ensured throughout the different erection stages. The...
The use of stainless steel in structures has been improved; nevertheless, the application of this material is not considered trivial by most designers, as there as still limited design codes providing specific rules. Current codes provide conservative approaches in certain cases, which do not corroborate with the objective of reducing the initial c...
With the need of renovation in the current timber structures, use of a cement based layer is a popular solution, which improves the structural integrity and increases the structural mass. In this paper, the use of a lightweight concrete with dowel type connections is investigated since such a combination can serve for both new and existing structur...
With an increase in trend to integrate more wood into the construction industry, timber concrete composite (TCC) solutions are an efficient manner to overcome the limitations of timber. In the current literature, there are various connections that have been investigated for TCC systems. One with sufficient performance to target massive construction...
Long spans in timber concrete composites (TCC) is the next step of improvement that is ambitioned by the industry and designers for more efficient structures. With Perfobond connections, which are originally developed for steel-concrete composites (SCC) constructions, targeting longer spans in TCC is feasible. In this paper, full scale TCC beams ar...
The use of lightweight concrete (LWC) with timber structures is an efficient solution for renovation and, with current high strength LWC, it is also an option for new constructions. In this paper, dowelled connections for timber concrete composite systems are experimentally investigated. Often, when renovating an existing building and implementing...
There has been a significant increase in stainless steel investigations related to steel construction in the last few years, contemplating numerical and experimental studies. This fact is associated with the excellent properties these materials can provide compared to carbon steel, such as corrosion resistance, durability, fire resistance, and adde...
In this paper, perforated shear connectors (perfobond), used extensively in steel-concrete composite (SCC) beams, are implemented in timber-concrete composite beams (TCC) and experimentally investigated. In contrast to its original use, the perfobond connector is connected with an adhesive to the timber beam while welded in the SCC solution. On the...
The paper presents the studies carried out on a big storage gas tank for the seismic vulnerability assessment and the retrofit through isolation system. This Gasometer, constructed in the early eighties, consists in a steel cylinder of 70 m height and 44 m diameter. The tank bearing structure is composed by a classical steel frame closed with curve...
Concrete-filled composite columns are widely used in the construction industry, exploiting the benefits of combining steel and concrete, providing, for instance, high load-bearing capacities and enhanced fire resistance. These solutions are extensively used in high-rise buildings and/or when high fire resistance performance requirements are imposed...
Composite structures have been applied more frequently because they are an economical structural solution with excellent structural performance. The interaction is guaranteed with the use of elements that transfer the forces between these two materials. The most common mechanical connections between steel and concrete are made through shear connect...
The connections play an important role in the overall behaviour of the structures. Therefore an adequate structural design taking into account both safe and economic criterion is necessary. The structural design of stainless steel bolted connections using actual codes can provide inadequate design capacity mainly due to the use of similar rules bas...
In timber constructions, mortar screed is often used to increase the floor's structural mass and to mitigate thermal, acoustic and vibration problems. As an alternative to solve this structural need, the use of low strength lightweight concrete is proposed in this contribution to further exploit composite behaviour between timber and concrete. A pe...
Shear connections have crucial importance in assuring the composite behaviour between the timber and the concrete in timber-concrete composites (TCC). Perfobond connectors were originally developed for steel-concrete composite structures to increase beam lengths by using their strong and stiff behaviour. Given the demonstrated efficiency of this ty...
In this paper, the use of low strength lightweight concrete in combination with glue-laminated timber (TLCC) is studied. Six series of push-out tests were conducted to assess the mechanical performance of the screw shear connection between these materials with a perpendicular and inclined (shear-compression) configuration with various screw diamete...

Although open‐to‐circular hollow section (CHS) connections are highly encouraged in the current structural steelwork industry thanks to the extensive range of advantages provided by the CHS columns, a complicated and...
This paper presents different types of two‐way and four‐way nominally pinned as well as moment resisting open‐to‐CHS connection configurations obtained via an innovative “passing‐through” approach and primarily proposed through the European research project LASTEICON. The two‐way moment resisting connections are emphasized in this article. The nonl...
In this paper, an experimental and numerical study were developed to evaluate the behavior of stainless steel bolted connections subjected to shear load until rupture, in which austenitic stainless steel 304 was used. In order to determine the material behavior, tensile coupon tests were performed. The numerical model was developed in Abaqus finite...
In concentrically braced frames, braces-to-adjacent member connections are suitable locations for the dissipation of seismic energy. If the implementation of dissipative connections does not compromise the global lateral stiffness of the structure, the compression braces can then be protected from buckling, while the structural ductility is increas...
Screw connections have an important role in the performance of Light Steel Framing (LSF) construction systems. In this paper, the behaviour LSF panels using screw connections subjected to lateral load is discussed and further insights are provided on the behaviour of such panels by experimental tests and numerical analysis.
Therefore, the main aim...
Resumo. A construção modular leve em aço (LSF, do inglês "Light Steel Framing"), é uma alternativa eficiente aos tradicionais métodos de construção in-situ. Um dos métodos da cons-trução modular, consiste na assemblagem de painéis (LSF) pré-fabricados e transportados para o local da construção. Na produção destes painéis em LSF, é usual a utilizaçã...
Recent earthquakes demonstrated the susceptibility of industrial plants to such events. In extreme situations, as the earthquake in Fukoshima (Japan), the impact of the seismic action on these infrastructures leads to catastrophic results with consequences for the environment, neighbour population and economy. The impact of an earthquake on an indu...
The resistance of bolted lap shear connections in bearing is traditionally evaluated by considering an equal distribution of internal forces amongst the bolts. In fact, such an assumption may only be seen as the result of a plastic redistribution of the internal forces, what requires shear ductility in the vicinity of the bolts. In the present pape...
This paper presents the first part of a numerical study to simulate composite beam to reinforced concrete wall joints using the finite element software ABAQUS. In detail, several benchmark examples dealing with different components of the joint are simulated in the validation and calibration process of the finite element package. Moreover, these si...
This paper presents the second part of a numerical study that aims to reproduce the behavior of a novel type of joint between a composite beam and reinforced concrete wall using the finite element software ABAQUS. The joint configuration was developed within the RFCS project “InFaSo”, which provided the experimental results. In a preceding paper, t...
One of the research topics related to composite steel-concrete structures is the connection between steel and concrete members-namely, the design of the anchorages. Because the design of steel-reinforced anchorages using the available methodologies (namely, from the CEB Design Guide, CEN/TS 1992-4, and ACI 318-08) may lead to excessively conservati...
A design model for composite beam-to-reinforced concrete wall joints is presented and discussed in this paper. The model proposed is the component method extended to this type of joint. The characterization of the active components is therefore performed in terms of force-deformation curves. In this type of joint, special attention is paid to the s...
This paper presents innovative solutions for connecting steel and composite beams to structural reinforced concrete walls, as developed within the RFCS research project “InFaSo”. Two types of joints were studied: pinned and moment-resistant. The evaluation of the behaviour of the joints was performed experimentally and complemented by the developme...
This paper describes the development and calibration of a structural monitoring system installed in a 80 meters high steel wind tower supporting a 2.1 MW turbine Wind Class III IEC2a erected in the central part of Portugal. The several signals are measured at four different levels and include accelerations, strains on the tower wall and inside the...
Innovative solutions for assembling joints of a tubular tower for wind turbines were studied and the project provides a background for design. This solution is simpler to produce and 80 % less expensive than traditional flange connection. Our feasibility study at the production plant indicates that the towers would be easy to assemble in situ. In a...
The studied joint configuration is illustrated in Fig. 1. Two different transfer areas may be distinguished. The upper area consists of a reinforced concrete slab where the longitudinal reinforcement is anchored in the reinforced concrete wall. The wall and the slab were concreted at different times and therefore, no shear is assumed to be transfer...
In order to achieve a full plastic distribution of forces in a shear bolted connection, ductility is required to the steel plate and to the plate-bolt contact zone in the firstly loaded bolt rows. Knowing that bolts present a brittle behavior, deformation capacity has to be obtained from ductile components as the plate-bolt in bearing. In the prese...
In this paper is described the monitoring system developed for the long term monitoring of a wind turbine steel tower. The measured data include acceleration at various levels, strain on the tower wall, inclination on the upper part and temperature. To correlate with the wind velocity and direction, nacelle position and status and rotor speed the c...
