Analysis on Load Bearing Capacity of Column with Different Diameters of Steel Tube under Horizontal Displacement
In order to analyze load bearing capacity of column with different steel tube diameters under horizontal displacement, and provide reference for further study about seismic performance of column which is called CFRP steel reinforced concrete filled with steel tube concrete column, this paper makes the nonlinear finite element analysis on this column by using ABAQUS. The load–displacement curves of the specimens with different steel tube diameters are acquired by establishing model, choosing constitutive relationship, making unit types and mesh settings, and then analyze the influence of different steel tube diameters on load bearing capacity of specimens. The curves show that with the increasing of steel tube diameters, the slope of curves in the elastic stage increases, besides, maximum point of load–displacement curves in the elastic stage is increasing. The results show that only with horizontal displacement, the slope of curves and the bearing capacity in the elastic stage is increasing with the increasing of diameters, it is clearer when the horizontal displacement is small.
