【摘要】 对一T形柱进行了有限元实体模型轴心受压承载力分析,并将其轴心受压承载力—变形全曲线转化为Beam189单元的本构模型,进而利用Beam189单元对T形柱构件进行受剪承载力模拟,并与其低周往复加载试验结果及JG J 149-2006混凝土异形柱结构技术规程计算结果进行分析比较。研究表明,利用该方法计算异形柱受剪承载力与《规程》计算结果非常相似,与低周往复加载试验结果相比较高。更多还原

【Abstract】 It undertakes the finite element real body model axial stressed loading analysis on some T-shaped column,transforms the axial stressed loading,the transformation whole curve to be Beam189 unit constitutive model,and adopts Beam189 unit to have the shearing loading simulation on T-shaped column part,analyzes and compares the results of the low cycle reciprocating loading experiment and the calculation results for JGJ 149-2006 Technical Regulation of Concrete Special Column Structure,proves by the results that the shearing loading of the special column has the similar calculation results with the Regulation,while its results is a little higher that the one of the low cycle reciprocating loading experiment.更多还原
