薄壁钢板组合截面PEC柱的非线性有限元分析

摘要

To investigate the performance of PEC column with thin-walled built-up section, the FEM software named ABAQUS was adoppted to analyze 4 test specimens of PEC columns,compared with the test results,the effective behaviors of hoop space,layout of strong or weak axis,axial compression ratio and concrete on the loading-carrying capacity and deformance patterns of PEC column were derived,it provided some suggestions for the relevant researchers and designers.%为了研究薄壁钢板组合截面PEC柱的力学性能,采用ABAQUS软件,建立有限元分析模型,对4个PEC柱试验试件进行有限元模拟研究,并与试验结果对比,得出了柱横向拉结筋设置间距、强弱轴布置方式、轴压比以及混凝土等因素对PEC柱承载力和变形能力的影响关系,供相关研究和设计人员参考.
