The Finite Element Analysis

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.

In this paper, we study the effect of rate of steel bone for the hysteretic property of cross steel reinforced concrete special-shaped column in the same horizontal cyclic load when they have the same axial compression ratio. We use the finite element analysis software ABAQUS to get the deformation pattern by establishing models of column, choosing the constitutive relation reasonably and determining the type of unit. We apply the data of simulation to draw the hysteretic curve and the skeleton curve, and then we analyze the hysteretic property by using the curve and the data. By contrast, it can be seen that the hysteretic property of column enhance with the increasing of rate of steel bone, and the ultimate bearing capacity of column also enhance with the increasing of rate of steel bone.

In this paper, the finite element analysis software ABAQUS is used to study the hysteretic property of cross steel reinforced concrete special-shaped column in different axial compression ratios. In the same condition, we can get the deformation diagram of cross steel reinforced concrete special-shaped column which the axial compressive ratio is 0.0, 0.4, 0.5, 0.6, 0.7 and 0.8 by changing the axial load of the column, then extract the hysteretic curve and skeleton curve. By contrast, it can be seen that the hysteretic property of column reduce with the increasing of axial compression ratio, and the ultimate bearing capacity of column also reduce with the increasing of axial compression ratio.

The ultimate load-bearing capacities of axially-loaded steel tube composite column filled with steel reinforced concrete under three-dimensional stress based on the unified strength theory are analyzed in this paper. The influence of thickness-length ratio and scale effect are considered by introducing the reduction factor of equivalent constraints and concrete strength reduction factor, respectively. The nonlinear three-dimensional finite element analysis of the steel tube composite column filled with steel reinforced concrete is performed by the finite element software ANSYS. The numerical and the analytical results are compared with experimental results and good agreement can be observed. A series of numerical simulation technologies is studied and described in detail, such as selecting element type, defining material model of steel and concrete, establishing global finite element model with discrete reinforced bars elements, applying loads to the specimens, and setting solution controls option. The results indicate that ANSYS finite element software may well simulate the behavior of the steel tube composite column filled with steel reinforced concrete under axial compression through reasonably selecting parameters.
