弹塑性动力时程分析若干问题的分析与探讨
|
摘要
分析并探讨了弹塑性动力时程的主流分析软件(ABAQUS)关于混凝土及钢管混凝土的本构关系、特殊情况下单元的选取、高振型阻尼比的影响、混凝土在重力作用下的本构关系和算法选择等方面的问题,并提出了相应解决方法,经理论分析与实际工程验证,其方法是可行的。此外,还对弹塑性动力时程分析软件的使用提出了建议。
In this paper,several problems of elastic-plastic dynamic time-history about constitutive relation of concrete and steel tube-restrained concrete,selection of element in special case,influence of higher modes damping ratio,selection of algorithm under the load of gravitity are analyzed,and the actual solution are given.Besides,some suggestions about using the software of elastic-plastic dynamic time-history analysis are put forward.
