摘要

利用ANSYS/LS-DYNA软件，对脉冲荷载作用下结构底面有无固定钢板时混凝土结构的动力特性及钢板的抗层裂性能进行了数值分析，对比分析了两种情况下混凝土结构的应力-时程特征，研究了边界效应对混凝土-钢板结构抗层裂性能的影响。分析表明，底面固定钢板能够有效地减小相邻混凝土的最大拉应力，提高其抗层裂性能；边界效应对混凝土层裂现象并无影响。此研究成果可为相关工程的设计、施工提供参考。

Abstract

The dynamical traits and performance of spall-resistant steel panel in the structure with or without steel panel under impulsive load are simulated by the software ANSYS/LS-DYNA. On the analysis of the results of two cases

the rule of structure’s stress and the boundary effects on capability of steel panel are presented. Results reveal that the steel panel can effectively reduce the element’s maximal stress adjacent to the steel panel

improve the performance; boundary effects don’t affect the spalling. The work will provide reference for the design and construction of projects concerned.
