［摘要］針對工程中存在的塔樓偏置、高位轉(zhuǎn)換、平面不規(guī)則、長寬比超限、高寬比接近規(guī)范限值、結(jié)構(gòu)超長等情況，采用概念設(shè)計(jì)方法對結(jié)構(gòu)體系進(jìn)行選型，并對整體布置進(jìn)行優(yōu)化；采用型鋼混凝土和預(yù)應(yīng)力混凝土技術(shù)，對關(guān)鍵構(gòu)件和薄弱部位進(jìn)行內(nèi)力調(diào)整，以增強(qiáng)結(jié)構(gòu)構(gòu)件的承載能力和變形能力；對超長結(jié)構(gòu)配置合理的溫度應(yīng)力鋼筋，同時采取施工措施減小溫度應(yīng)力；對大空間樓屋蓋的強(qiáng)度、舒適度進(jìn)行計(jì)算分析，以確保結(jié)構(gòu)的安全可靠。結(jié)果表明，整體結(jié)構(gòu)各項(xiàng)計(jì)算指標(biāo)均滿足相應(yīng)規(guī)范要求。［關(guān)鍵詞］塔樓偏置; 高位轉(zhuǎn)換; 托柱轉(zhuǎn)換; 盆水效應(yīng); 超長結(jié)構(gòu); 大空間中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2015)15-0046-05
Structural design of an office building in XinjiangYe Lihuan1, Liu Changpeng1, Zhou Ting1, Tao Li2(1 Building and Planning Design Research Institute of General Logistics Department of PLA, Beijing 100036, China; 2 Shanghai Electronics Engineering Design & Research Institute Co., Ltd., Shanghai 200083, China)Abstract:The building has characteristics of tower eccentricity, high-level conversion, plane irregularity, out-of-code length-width ratio, height-width ratio close to the code limit and super long structure. The conceptual design method was used to carry out structural system selection and the overall layout was optimized. Steel reinforced concrete and prestressed concrete techniques were used to carry out internal force adjustment of key components and weak parts to strengthen the bearing capacity and deformation capacity of the components. Reasonable temperature stress rebar were deployed for super long structures and construction measures were taken to reduce temperature stress. The comfort and strength of large space floor and roof were calculated to ensure safety and reliability of the structure. Results show that all the calculated structural overall indexes can meet the requirements of the relevant codes.
Keywords:tower eccentricity; high-level conversion; column transformation; effect of water in the basin; super long structure; large space
