复杂受力状态下密肋复合墙体框格有限元模拟
|
摘要
基于通用有限元计算分析软件并结合自定义材料子程序模型,对水平往复荷载及轴压力下的密肋复合墙体框格试件进行了梁式建模、壳式建模及梁壳式建模方式下的数值模拟.基于不同有限元建模方式,混凝土材料模型分别选用汪混凝土本构模型和经典混凝土弹塑性+断裂本构模型,而钢筋材料模型统一采用汪钢筋本构模型.通过计算结果与试验结果的对比分析,探讨了影响往复荷载下密肋复合墙体框格数值模拟的主要因素.
A ribbed frame grid specimen under laterally cyclic and axial loading in literature was numerically simulated by three kinds of finite element modeling method: beam-based,shell-based,and beam-shell-based.Based on different modeling methods,the concrete constitutive model adopted WANG concrete constitutive model or classical concrete elastic-plastic+fracture constitutive model,respectively,and steel constitutive model used WANG steel model.By comparison of tests and calculation,main factors on numerical simulation of the frame grid under complicated loading conditions were discussed,and by comparing different ways of modeling.
