网壳结构在大跨度空间结构中应用广泛.为对杭州银泰购物广场采光顶大厅网壳结构进行整体设计和稳定性验算,采用Midas软件对恒载、活载、风洞试验所得到的风载、雪载、地震、支座位移等作用下的网壳结构不断调整使其满足设计要求,并按规范进行了整体稳定性分析.杆件应力和结构的整体稳定基本符合规范要求,但在荷载组合下的结构最大变形超出了规范要求,恒载下的变形可通过反拱来改善外观,活载下变形满足规范限值.本文设计基本满足设计要求.
Reticulated shell structure is widely used in long-span space structure.In order to design and stability check the reticulated shell structure of the lobby of Yintai shopping mall in Hangzhou, Midas software is used to test the wind load , Under the action of snow load, earthquake and bearing displacement, the structure of the reticulated shell is continuously adjusted to meet the design requirements and the overall stability analysis is carried out according to the specifications. The overall stability of the bar stress and structure basically meets the requirements of the code, Under the combination of the maximum deformation of the structure is beyond the requirements of the standard, deformation under constant load can be improved by reverse arch appearance, deformation under live load to meet the regulatory limits.The design of this paper basically meet the design requirements.
