ABSTRACT:

A full-scale seismic test on a completely prefabricated steel frame has been conducted and reported. In order to simulate the cyclic behavior of this type of frame, and provide a simple and accurate simulation for similar structures, a method of finite element (FE) modelling and analysis was developed. In the FE model, hollow section box columns, I-section beams, end-plates, inner diaphragms and stiffeners were modelled using shell elements; high strength bolts and concrete slabs were modelled with solid elements; and flexible braces and rebar were modelled with truss elements. Results evidenced that the proposed numerical method could accurately simulate the static and cyclic performance of bolted T-stub connections, bolted tension splices, bolted end-plate steel joints, bolted end-plate composite joints and flexibly braced steel frames. The seismic behavior including deformation capacity, cyclic behavior, horizontal loading performance, energy dissipation and stiffness degradation of this type of completely prefabricated steel frames could be accurately simulated by the proposed finite element model.
