摘    要:选取由表面钢板、拉结筋、剪力钉及混凝土组成的钢板混凝土结构墙为研究对象,运用经典显式非线性动力分析软件ANSYS/LS-DYNA,基于荷载时程分析法进行了一系列影响钢板混凝土结构墙抗冲击性能的参数敏感性分析。这些参数包括:墙体厚度、钢板厚度、拉结筋直径与间距等。分析结果表明,以上参数均会影响墙体的抗冲击性能,尤其是墙体与钢板的厚度以及拉结筋的间距。本文的研究工作对于核电厂核岛厂房钢板混凝土结构外墙的设计具有一定的指导与参考意义。

关 键 词:固体力学  抗冲击性能  荷载时程分析法  钢板混凝土结构墙  敏感性分析

Abstract:In this paper, to study preventive ways against incidents involving the impact of steel plate concrete (SC) structures, the steel plate concrete (SC) walls composed of surface steel plates, tie-bars, shear studs and concretes were selected as the object of investigation. The impact analysis of the walls was performed using ANSYS/LS-DYNA, the FEM code, based on the force vs. time-history analysis, in which a series of numerical sensitivity studies were conducted to evaluate the effect of several parameters affecting the behavior of the SC wall. These parameters include the thickness of the wall, the thickness of the steel plate, and the diameter and space of tie bars. The results show that they all have an effect on the impact resistance of the SC wall. This is especially true with the thickness of the wall and the steel plate, and the spacing distance between the tie bars. These studies will serve as guidance and reference for the design of SC structures that are to be used in nuclear power plant buildings.
Keywords:solid mechanics  behavior of impact resistance  force vs  time-history analysis  steel plate concrete wall  sensitivity analysis
