［摘要］杭州奧體中心體育游泳館長約609m，寬約200m，由下部主體混凝土結(jié)構(gòu)和屋蓋鋼網(wǎng)殼結(jié)構(gòu)組成。介紹了工程的結(jié)構(gòu)體系、設(shè)計(jì)難點(diǎn)和主要分析結(jié)果。著重闡述了設(shè)計(jì)中的一些關(guān)鍵問題及相應(yīng)的處理措施，包括結(jié)構(gòu)的超限情況及抗震性能化設(shè)計(jì)、屋蓋自由曲面鋼網(wǎng)殼設(shè)計(jì)、有粘結(jié)預(yù)應(yīng)力梁設(shè)計(jì)、溫度應(yīng)力計(jì)算和彈塑性分析等。

Abstract: The sports and swimming stadium of Hangzhou Olympic Center is about 609m in length and 200m in width. It consists of the main concrete structure at the bottom and the steel reticulated shell roof. The structure system, difficulties in the designing process, and the main analysis results of this project are introduced. Some key points are focused on during the designing process, including the situation of this beyond-code-limits structure, the seismic design, the design of free-form surface steel reticulated shell roof, the design of bonded prestressed beams, the calculation of thermal stress, and the elastic-plastic analysis, etc.

Keywords: beyond-code-limits structure; long span reticulated shell; parameterized curved surface; over-length concrete structure; prestressed beam; thermal stress; elastic-plasticity
