钢管混凝土构件在冲击荷载作用下的模拟分析

Numerical simulation of relation of steel pipe concrete components transmutationand impact energy under cross ranged impact

运用LS-DYNA显示有限元程序,分析了钢管混凝土构件受到侧向冲击物冲击时,钢管混凝土的挠度与冲击部位、冲击能量、含钢率、混凝土等级之间的关系,建立了挠度和冲击能量之间的关系式以及冲击部位不同时挠度之间的关系。

This paper introduced showing limited meta program with LS-DYNA, analyzed the relation between steel pipe concrete flexibity and impact positon, impact energy, steel ratio, concrete gradation, restriction of boundary when steel pipe concrete components be impacted by cross ranged impact block, meanwhile established relation between flexibity and impact energy, and relantion of different impact position.
