The Element Analysis on Hysteretic Property of Cross Steel Reinforced Concrete Special-shaped Column in Different Concrete Strengths

摘要

In order to study the hysteretic property of cross steel reinforced concrete special-shaped column, we use the finite element analysis software ABAQUS to build 6 models of cross steel reinforced concrete special-shaped column in vertical load and horizontal cyclic load. We observe the mechanical process and the failure pattern in different concrete strength and extract hysteretic curve and skeleton curve. By analyzing two curves we know the influence of concrete strength. Simulation results show that the hysteretic property of column is better with the increasing of concrete strength and the column also has higher bearing capacity.
