电梯升降式立体停车库钢结构骨架的结构分析

Analysis the Steel structure of the lift park garage stereoscopic garage

设计了立体车库的钢结构骨架,运用有限元方法对钢结构骨架进行模型化,按照实际要求对车库的受力情况进行假设,找出了立体车库的钢结构骨架的最大应力单元和最大变形单元,它们都小于许用应力和许用变形量,验证结构设计的可靠性。为进一步降低钢结构骨架的重量,建立了钢结构骨架的数学模型,对钢结构骨架进行了优化设计,使钢结构骨架的整体重量减轻许多,并提高了电梯升降式车库的经济性。

The steel structure framework of the stereoscopic garage was designed through the analysis and the compare. The model on the steel structure framework was set up by the finite element method. The force that the garage suffered was supposed according to the fact. The element that suffered the press more greatly and the element that distorted mostly were found out and they were less than the permitted stress and the permitted distortion. The reliability of the structure was validated. In order to more decrease the weight of the steel structure framework, the optimal design on the steel structure framework was carried through with Lagrange method, which made the weight of the steel structure framework become more light and made the garage more economical.
