摘要
针对门式刚架轻钢结构,基于有限元理论,利用大型有限元分析程序对门式刚架轻钢结构进行三维实体建模和模态分析,得到了此结构的模态分析结果,结果表明当频率较小时,在X方向会产生较大结构破坏位移,而随着外部激振频率的增加,结构破坏位移主要产生在Y方向。
According to the portal frame light steel structure, the study adopts the large finite element analyzing program to undertake the three- dimensional solid modeling and model analysis based on the finite element theory, concludes the model analysis result of the structure, and proves by the result that larger structural damaging displacement occurs at the direction of X when the frequency is little, and the structural damaging dis- placement will be transferred to the direction of Y when the external excitation frequency increases.
