摘　　要：为了对全预制框架柱的受力性能进行评价,本文应用ANSYS对其进行非线性有限元分析,并与相同条件下的整浇柱和全预制框架柱的试验结果进行对比。结果表明,全预制框架柱与整浇柱破坏形式相同;极限承载力和最大侧移相当,略小于试验结果;裂缝分布、应力和应变有一定差异。本文还对全预制框架柱的薄弱部位一柱齿进行了受力分析。The bearing performance of tectonic total-precast frame column was analyzed with nonlinear finite element method of ANSYS,the consequences were compared with the cast-in-suit ones and the experimental results of total-precast frame column in the same situation.It can conclude that the damage form is the same between total-precast frame column and the cast-in-suit ones;the limit bearing capacity and maximum lateral displacement are equivalent, and less than the experimental results;the distributions of crack,stress and strain have some difference among them. The weak position that is alveolus was analyzed.
