摘要: 布吉文體中心項目采用鋼框架結(jié)構(gòu)體系,其建筑造型獨特,立面復(fù)雜,因大跨度、大懸挑存在結(jié)構(gòu)轉(zhuǎn)換和多項不規(guī)則。 介紹了項目的結(jié)構(gòu)特點和設(shè)計思路,根據(jù)建筑功能需要,對各樓層平面和上下樓層間的空間關(guān)系進行梳理,確定了合理柱網(wǎng)和結(jié)構(gòu)形式。 采用 YJK 和 ETABS 兩個軟件進行了結(jié)構(gòu)在多遇地震和風荷載作用下的計算分析,得到了振型周期、剛重比、風振加速度、最大層間位移角、框架梁撓度、樓蓋舒適度、關(guān)鍵構(gòu)件和節(jié)點受力性能等重要的分析結(jié)果。 結(jié)果表明:柱網(wǎng)的優(yōu)化最大限度地減少了結(jié)構(gòu)轉(zhuǎn)換,局部懸挑綜合運用了桁架、斜柱的不同轉(zhuǎn)換形式,傳力路徑簡單明確,結(jié)構(gòu)計算各項指標滿足規(guī)范要求,結(jié)構(gòu)設(shè)計合理、安全、可靠。

Abstract: Buji Culture and Sport Center project adopts steel frame structure system with unique architectural shape andcomplex facade. Due to large span and large overhang,there are structural transformation and irregularities. The structuralcharacteristics and design ideas of the project were introduced, the spatial relationship between each floor plan up and downaccording to the needs of building functions was combed, the reasonable column grid and structural form were determined.YJK and ETABS software were used to calculate and analyze the structure under the frequent earthquake and wind load,and important analysis results such as vibration mode period, stiffness weight ratio, wind vibration acceleration, maximuminter story displacement angle, frame beam deflection, floor comfort, stress performance of key components and joints wereobtained. The results show that the optimization column grid minimizes structural transformation, different transformationforms of truss and inclined column are comprehensively used for local cantilever, the force transmission path is simple andclear, and each index of structural calculation meets the specification requirements, which is reasonable, safe and reliablefor structural design.
Keywords: Buji Culture and Sport Center; steel frame structure system; large span; large overhang; structural transformation; body retraction; comfort analysis
