Numerical Analysis of Bolted Connectors in Prefabricated Steel-Lightweight Aggregate Concrete Composite Beams
This paper presented a three-dimensional (3D) numerical model to explore the shear behavior of bolt connections embedded in steel-lightweight aggregate concrete composite beams (SLACCBs) by utilizing the ABAQUS software. Nonlinear geometric effects and material nonlinearities were considered in the finite element (FE) modelling. The accuracy and reliability of the FE modelling were validated against the push-off tests initially. Subsequently, the basic shear properties of the bolted connection embedded in SLACCBs were studied and compared with that of the bolted connection embedded in the normal concrete (NC) slab by applying the verified FE modelling. Meanwhile, the effects of the concrete strength, concrete density, bolt diameter, and bolt tensile strength on the shear behaviour of bolt connection embedded in SLACCBs were also investigated by extensive parametric studies.
