摘　　要：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。The internal force and displacement of the cable-membrane structure of stadium grandstand in Hangzhou were checked again, because all steel components were built by lower level brand of steel during the construction process. In order to make the structure work normally, the reinforcement for the existing structure was researched. The construction condition and reinforcement scheme were analyzed in detail by self edit program and finite element software SAF2000. Finally the optimal reinforcement scheme was proposed, including structure system strengthening and section reinforcement for steel components. This scheme is relatively operable and the structure can work normally in bad load conditions after reinforcement.
