Abstract:
Based on the concept of dispersed elements corresponding to different mechanical functions of structural materials in partially encased composite(PEC)columns, a finite element model of partially encased composite column was built up by dispersing the concrete into elasto-plastic springs elements in perpendicular directions. By using ANSYS finite element software, nonlinear analysis was carried out for simulation of the hysteretic behavior of 6 PEC columns under cyclic loads. The load-displacement curves were obtained and compared with experimental curves. The result demonstrates that the curves of numerical simulation and experiments are correspondence with each other, which means the simulation is valid. The finite element model can simulate the elasto-plastic behavior and seismic properties of PEC columns with the advantages of easy constitution of model, feasible result and high efficiency, and it can be used in parameter analysis for the hysteretic behavior of members.
