摘要
利用LS-DYNA有限元软件,使用分块求逆Lanczos方法对某防护门结构进行了模态分析,并研究了配筋率对其模态的影响,得出了相关结论,为求得防护门结构的简化计算解析解奠定了基础。
The paper adopts LS-DYNA finite element software, undertakes the model analysis of some protective doors structure by using the blocking inversion Lanczos method, researches the influence of steel ratio on its model, and achieves some relative conclusions, so as to lay the foundation for achieving the simplified calculation analytical solutions of the protective door structure.
