Fully prefabricated steel-concrete composite (PSCC) structures come into being when precast concrete (PC) floor slabs are used to replace cast-in-situ concrete slabs, which possess the advantages of time-saving and convenient construction without or with less cast-in-situ concrete. However, segmented PC slabs decrease the integrity of composite fra...
Steel-concrete composite box girders with corrugated steel webs (CSWs) are broadly used in bridge engineering, in which the joints between top RC slabs and steel girders with CSWs are usually subjected to transverse bending moments caused by off-center vehicle loads. Stud connectors arranged in the joints usually bear repeated pull-out forces in th...
This study numerically investigates the seismic responses, bearing capacities, and fragilities of long-span truss structures (LSTSs) in ultra-high voltage substations subjected to near-fault pulse-like (NFP) and far-field (FF) earthquakes. The finite element model established in ABAQUS software considers the tower-line dynamic coupling effect, and...
This paper presents the results of a detailed experimental investigation of the fire behaviour of prefabricated demountable composite beams (PDCBs) with bolted shear connectors. Four full-scale standard fire resistance tests were conducted to evaluate the performance of PDCBs with varying degrees of shear connection (65% and 33%) at ambient tempera...
This paper presents a detailed experimental investigation of the fire behaviour of prefabricated demountable composite beams (PDCBs) with stud shear connectors. Four full-scale tests were conducted to evaluate the performance of PDCBs under varying shear connection degrees (65% and 33%) and fire protection measures (with and without fire protection...
This paper presents the results of a detailed experimental, numerical and analytical study to investigate the flexural bending performance of prefabricated demountable composite beams (PDCBs) with bolted shear connectors. Four full–scale tests were carried out for two profiled steel decking configurations (parallel and perpendicular to the steel se...
Steel–concrete composite box beams are widely used in bridge engineering, which might bear transverse and longitudinal bending moments simultaneously under vehicle loads. To investigate the fatigue performance of joints between the steel girders and the top reinforced concrete (RC) slabs under transverse bending moments, a reduced scale joint betwe...
Bolt shear connectors used in prefabricated steel–concrete composite beams can be arranged into a group to enhance the construction efficiency, which will cause the multi-bolt effect and further affect the shear performance of bolt connectors. This paper developed three-dimensional finite element models of push-out specimens to investigate the shea...
Four prefabricated steel–concrete composite beams (PSCCBs) with grouped bolt shear connectors were designed and tested to investigate their flexural performance under positive bending moments. The effect of shear connection degrees and segmented precast concrete (PC) slabs on the flexural performance of PSCCBs was investigated. Experimental results...
The flexural behaviors of prefabricated steel-concrete composite beams (PSCCBs) with segmented precast concrete (PC) slabs were investigated through four-point bending tests. Experimental results showed that all the tested PSCCBs failed in flexural failure. The PSCCBs with segmented PC slabs exhibited good deformability and ductility, and the displ...
An analysis of the effect of vehicle loads on the fatigue life of local arch bridge suspenders in Southwest China was conducted by generating vehicle statistics, creating a fatigue vehicle model, and developing a fatigue life prediction method: First, the Midas model of an arch bridge was established, a random vehicle flow simulation was conducted...
Basalt fiber reinforced polymer (BFRP) bars are ideal substitutes for steel reinforcement due to their excellent mechanical performance, which could avoid energy consumption and carbon dioxide emission during the production of construction steel. Concrete structures reinforced with BFRP bars encounter the collapse risk under an occasional accident,...
An extensive numerical study was carried out due to the concern that head-sectional damage caused by corrosion poses a threat to the tensile performance of headed stud connectors. Three-dimensional finite element models of pull-out tests were established, with both material and geometric nonlinearities being considered. In particular, the concrete...
p>Bolt shear connectors have the advantage of efficient installation and demolition when used in prefabricated composite beams. When bolt shear connectors are damaged in the service period and replaced by new ones, the sheer performance of the replaced bolts will be affected by the existing structural damage. This paper experimentally investigates...
To investigate dynamic collapse performance of a steel-concrete composite frame structure after a middle column failure,tests with a column removed were conducted on two 1/3 scaled specimens of composite frame substructures.Test results showed that when the additional weights of 30 kN and 60 kN are hung on a steel-concrete composite frame beam,resp...
To evaluate the influence of openings in floor slabs on the collapse performance of steel-concrete composite floor (SCCF) systems, 2 one-third scale 1 × 2 bay SCCF substructures were fabricated and tested under static load up to final collapse in an exterior-column-removal scenario. The experimental results indicated that arch-shaped and radial cra...
Reinforced Concrete (RC) flat slab structures are mainly composed of load-bearing columns and RC slabs, which are vulnerable to collapse once one or several local load-bearing columns fail due to accidental loads such as terrorist bomb attack or vehicle collision. To investigate the progressive collapse performance of flat slab structures after the...
Steel-concrete composite beams with corrugated steel webs (CSWs) usually have concrete flanges that are prone to crack under tension, and an innovative posttensioned composite beam (IPCB) with CSWs has been proposed previously to overcome this shortcoming. Here, an IPCB with CSWs is manufactured and submitted to a flexural test to investigate its f...
Prefabricated steel-concrete composite beams, which consist of steel beams, prefabricated reinforced concrete (RC) slabs, as well as shear connectors, are getting widely used in engineering structures. As a kind of post-installed shear connector, shear performance of the bolt connector has been broadly investigated in recent years, because their ap...
Hangers are important tensile members in half-through arch bridges and through arch bridges (HTABs and TABs). The floating deck structures of HTABs and TABs will commonly produce longitudinal deformation and rotate under the effect of temperature and the temperature gradient, which will cause bending deformation at anchorages of fixed-end hangers....
Accidental loads such as explosion and vehicle impact could lead to failure of one or several load-bearing members in the structures, which is likely to trigger disproportionate progressive collapse of overall structures. Prestressed concrete (PC) frame structures are usually at great risk of collapse once load-bearing members fail, because the mem...
Six concrete beam-column frame sub-assemblages reinforced with basalt fiber-reinforced polymer (BFRP) bars in the frame beams were designed to investigate the collapse resistance after a middle column removal. Effect of parameters, including span to depth ratio of frame beams, prestressing, as well as material types of stirrups in the beams, on the...
To evaluate the ductility and energy dissipation capacity of the beam with concrete-encased steel truss, eight specimens with different types of steel truss, reinforcement ratios, and shear span ratios were tested by low-cyclic loading regime. The results indicated that beams with concrete-encased steel truss performed plumped load–displacement hys...

Permafrost under a roadway embankment is sensitive to temperature increments. Thermal stability of the underlying permafrost is mainly regulated by the solar absorption at the embankment surface. Multiple reflections between the embankment’s side slope and its adjacent ground surface may increase the solar absorption of the embankment but have not...
