摘要:
基于按结构材料力学功能建立离散化单元的思想,将混凝土离散为各向的弹塑性弹簧单元,建立了半组合结构柱的有限元模型。通过有限元软件ANSYS对6个半组合结构压弯构件进行了反复荷载作用下的滞回性能非线性分析,得到了其荷载-位移曲线,并与试验结果进行了对比。结果表明:由有限元模型得到的滞回曲线与试验曲线相似,模拟效果良好; 该有限元模型能模拟构件的弹塑性行为和抗震性能,建模简单,结果可信,计算效率高,可用于构件滞回性能的参数分析。
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.
