Finite Element Analysis on Circular Steel Tube Composite Column Filled with Steel Reinforced Concrete

Abstract:

The article analysis the seismic behaviors of circular steel tube composite column filled with steel reinforced concrete by the large finite element analysis software ABAQUS, adopted the load-displacement method and aimed at studying the mechanical properties of circular steel tube composite columns filled with steel reinforced concrete under horizontal low-cyclic loading, considering the degree of ductility, capacity of energy dissipation by the steel ratio and axial compression ratio. Under different axial compression ratios and steel ratios, the hysteresis curves and skeleton curves are carried out. Along with the increase of steel ratio, the deformation ability and ultimate bearing capacity are raised, but with the increase of axial compression ratio, the deformation ability becomes worse.
