【摘要】 用有限元程序ANSYS建立了(方钢管混凝土柱)钢管与混凝土柱的接触模型和固结模型,并进行了加载分析,与试验结果对比相差不大,模型是合理的.分析了固结模型和接触模型模拟结果的差别,对比发现二者在构件的某些局部上差别大,但对整体承载力影响不大,可用固结模型简化代替接触模型.更多还原

【Abstract】 In the paper,contacting model and consolidation model of(the concrete filled square) steel tube and column is modeled by the ANSYS software which is a finite element program.Results of loading analysis are consistent with the experimental results,therefore the models are reasonable.Comparing the differences of the two models,the results show that there is a world of differences in some local details,but the differences have little effect on the overall bearing capacity.So the consolidation model can replace the contacting model.更多还原
