［摘要］杭州上城區(qū)體育中心由于用地及功能等限制，采用一體多館建筑形式，主體結(jié)構(gòu)采用框架-剪力墻結(jié)構(gòu)體系，大跨度樓層采用鋼骨柱-鋼桁架承重體系，部分鋼骨柱間設(shè)置中心鋼支撐。進行結(jié)構(gòu)分析時，根據(jù)工程特點確定結(jié)構(gòu)的性能設(shè)計目標(biāo)，采用YJK，SATWE，MIDAS Building等軟件進行對比分析，針對扭轉(zhuǎn)不規(guī)則、樓板不連續(xù)、豎向構(gòu)件側(cè)向剛度和受剪承載力突變、單跨穿層柱等超限情況，對結(jié)構(gòu)采取相應(yīng)的加強措施，以實現(xiàn)整體結(jié)構(gòu)的抗震性能。此外，采用簡化計算法與SAP2000有限元分析法對大跨樓蓋的振動舒適度進行了核算。

Abstract:Shangcheng District Sports Center in Hangzhou adopts multi-stadia structure due to land use and functional constraints. The main structure adopts frame-shear wall structure system, and large-span floor system adopts steel reinforced concrete column and steel truss bearing system, and center steel support was set among the steel reinforced concrete columns. To analyze the structure, the performance design goal of the project was determined according to the characteristics. YJK, SATWE, MIDAS Building and other software were used for comparison and analyses. For out-of-code conditions of irregular torsion, discontinuous floor, lateral stiffness mutation of the vertical component, mutation of shear bearing capacity and single-span cross-layer column, corresponding measures were taken on the structure to achieve the overall seismic performance of the structure. In addition, the simplified calculation method and the SAP2000 finite element analysis method were used to calculate and check the vibration comfort degree of large-span floor.
Keywords:multi-stadia structure; complicated out-of-code structure; performance-based seismic design; vibration comfort degree of large-span slab
