Shear–slip failure in steel–concrete–steel composite beams with bidirectional webs
Abstract Steel–concrete–steel composite structures with bidirectional thin-walled webs (SCSBWs) are used to build large-scale structures. The presence of steel webs causes notable differences in shear behavior compared to other types of steel–concrete–steel (SCS) composite structures. In this paper, the shear–slip behavior of SCSBWs is studied through experiments and numerical simulations. Particularly, the numerical simulations cover a wide range of variations in the structural parameters to explore the effect of each parameter on the shear–slip behavior. A theoretical model to describe shear–slip in SCSBWs is proposed chiefly by introducing a slip reduction factor. The experimental and numerical data verified the proposed model, which also demonstrated acceptable accuracy and efficiency.
Highlights Shear–slip behaviors of SCS structure with bidirectional thin-walled webs are studied. Experiments are conducted and shear–slip coupled failure modes are observed. Numerical models are developed and parametric analyses are conducted. Theoretical model is proposed with emphases on thin-walled webs and interfacial slips.
