Analysis method of bearing capacity of three-dimensional garage structure based on finite element simulation

本文针对立体车库服役过程中金属结构的安全性问题,提出基于有限元仿真的车库结构承载能力分析方法。以GB/T 30024-2013《起重机金属结构能力验证》、GB 17907-2010《机械式停车设备安全规程》标准为依据,确定承载能力评价指标,根据载荷组合原则确定其典型工况,利用ANSYS软件搭建立体车库结构有限元模型,验证不同工况下的承载能力。以10层立体车库为例,验证方法的适应性与可行性。

Aiming at the safety problem of metal structure of three-dimensional garage in service, an analysis method of garage structure bearing capacity based on finite element simulation is proposed. Based on GB/T 30024-2013 verification of crane metal structure capacity and GB17907-2010 safety code for mechanical parking equipment, the bearing capacity evaluation index is determined, the typical working conditions are determined according to the load combination principle, and the finite element model of three-dimensional garage structure is built with ANSYS software to determine the verification results of bearing capacity under different working conditions. Taking the 10 storey three-dimensional garage as an example, the adaptability and feasibility of the method are verified.
