According to the structural system as well as the geological conditions, the manual hole digging piles were adopted by scheme comparision, which had larger bearing capacity and less cost. Beam string structure system was adopted in large span steel roof. Combination of design and construction helped release most lateral forces of the main concrete structure caused by large span steel roof. In order to reduce the roof drift and increase the lateral stiffness of the main structure, 8 shear walls were added, which fulfilled the architectural requirements as well. Some key vertical members were designed as elastic elements under fortification earthquake. Temperature stress was calculated for super long structure under the temperature load. The enlargement of the reinforcement ratio of floor slab helped reduce the temperature stress in the concrete as well as the shrinkage cracking.Keywords: gymnasium; beam string structure; treatment of super long structure; temperature stress; manual hole digging pile; performance-based seismic design作者簡(jiǎn)介：倪興惠，學(xué)士，工程師，Email:nixh@acctn.com。參考文獻(xiàn)［1］北京市建筑設(shè)計(jì)研究院.建筑結(jié)構(gòu)專(zhuān)業(yè)技術(shù)措施［M］. 北京:中國(guó)建筑工業(yè)出版社,2007.［2］GB 50011—2010建筑抗震設(shè)計(jì)規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2010.［3］白正仙，劉錫良，李義生.新型空間結(jié)構(gòu)形式——張弦梁結(jié)構(gòu)［J］.空間結(jié)構(gòu)，2001,7（2）：33-38.［4］符龍彪，陳才華，劉楓，等.中國(guó)國(guó)家博物館鋼桁架與混凝土結(jié)構(gòu)的合理連接研究與設(shè)計(jì)［J］.建筑結(jié)構(gòu)，2011,41（6）：26-30.［5］GB 50010—2010混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2011.
