QIAN Yue-hong, TANG De-gao, SONG Zhi-wen, et al. Numerical simulation of the dynamical trait and the effects of spall-resistant steel panel for underground structure under impulsive loads[J]. 2007, 28(S1).DOI:
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.
