［摘要］杭州市西湖區(qū)體育場(chǎng)看臺(tái)的索膜結(jié)構(gòu)因施工中所有鋼構(gòu)件采用低一級(jí)牌號(hào)的鋼材等原因，對(duì)該結(jié)構(gòu)重新進(jìn)行內(nèi)力和位移驗(yàn)算。為使其能夠正常工作，對(duì)現(xiàn)有結(jié)構(gòu)進(jìn)行加固。基于自編軟件和SAP2000有限元軟件對(duì)施工狀態(tài)和加固方案進(jìn)行詳細(xì)分析與比較，最終確定最優(yōu)的加固方案。該方案包括結(jié)構(gòu)體系加強(qiáng)和鋼構(gòu)件截面加固，且工程可實(shí)現(xiàn)性強(qiáng)，加固處理后結(jié)構(gòu)在惡劣荷載條件下能夠正常工作。

Abstract: 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 SAP2000. 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.

Keywords: cable-membrane structure; structure system strengthening; section reinforcement; SAP2000
