杭州市西湖区体育场看台的索膜结构因施工中所有钢构件采用低一级牌号的钢材等原因,对该结构重新进行内力和位移验算。为使其能够正常工作,对现有结构进行加固。基于自编软件和SAP2000有限元软件对施工状态和加固方案进行详细分析与比较,最终确定最优的加固方案。该方案包括结构体系加强和钢构件截面加固,且工程可实现性强,加固处理后结构在恶劣荷载条件下能够正常工作。
Xihu District, Hangzhou stadium bleachers structure due to the construction of all steel components with a lower grade grades of steel and other reasons, the structure of the internal forces and displacement again check. To enable it to work properly, the existing structure is reinforced. Based on the self-made software and SAP2000 finite element software, the construction status and reinforcement scheme are analyzed and compared in detail, and the optimal reinforcement scheme is finally determined. The program includes the strengthening of the structural system and strengthening of the steel member section, and the project is feasible, and the structure can work normally under severe load conditions after the reinforcement treatment.
