Finite Element Analysis of Steel Tube Bundle Composite Shear Wall with Different Constructions

Abstract In order to study the seismic performance of steel tube bundle composite shear wall with different constructions. Based on failure tests three specimens without end, studs and stiffener, a feasible numerical model is established by ABAQUS. The hysteresis curve energy dissipation coefficient, skeleton ductility were further analyses varying axial compression ratio spacing internal diaphragm. results show that stud group stiffener can effectively improve horizontal bearing capacity, capacity wall. Under condition low ratio, member increased 6.3%; high members stiffeners 4.5%; change between inner diaphragms walls has little effect their ductility.
