Finite Element Analysis on the Mechanical Properties of the Fundamental Elements of a Frame-truss Composite Wall

To address existing problems of lateral force resisting systems, the paper proposed the concept of a novel frame-truss composite wall. With the intention of testing its seismic performance, the finite element software ABAQUS was used to establish a nonlinear finite element model of the fundamental elements of the wall. By taking material nonlinearity into account, and with a simulative load test, the paper analysed the force performance of the wall elements. Specifically, the finite element analysis was first conducted on the embedded steel-rib short-leg shear wall, whose results agreed well with the test result. Thus the model was reliable. Then, on this basis, the paper analysed the influential factors of the failure mode and bearing capacity. Finally, the paper provided reasonable parameters for the fundamental elements of the novel wall, which lay foundation for further research.
