医院门诊大楼大跨悬挑钢结构雨棚设计方案优化OA

In order to ensure the clearance requirements of the cantilevered canopy in the hospital outpatient building,a design scheme of unsupported cantilevered canopy needs to be adopted.This paper takes the large-span canopy of the outpatient medical technology building of Changchun Obstetrics-Gynecology Hospital,which is over 8 meters long,as the background.Based on the actual construction situation,a three-dimensional finite element analysis model is established.Considering the unfavorable conditions of combining wind load and self-weight load,the structural design of the original steel canopy was optimized based on the internal forces and deformations of the structure.Firstly,the internal force and deformation of the original design method of the lower diagonal brace are analyzed,and an optimized design scheme that can meet the requirements of the design specification and the lower part without slant support is proposed,which meets the requirements of the out-patient building's overhanging canopy for the lower clearance.This optimization scheme can provide a reference for the design of similar large-span canopy.
