［摘要］浙江音樂學(xué)院體育館下部采用鋼筋混凝土框架剪力墻結(jié)構(gòu)，上部鋼結(jié)構(gòu)按建筑功能和校區(qū)整體風(fēng)格采用空間折板桁架結(jié)構(gòu)。該結(jié)構(gòu)屋面和兩側(cè)墻面均為空間折板桁架，兩側(cè)墻面的桁架內(nèi)側(cè)豎桿有效地埋入下部混凝土墻柱中，呈沿東西方向的“手風(fēng)琴”造型。為了保證分析結(jié)果的準(zhǔn)確性，采用上下部結(jié)構(gòu)整體模型，對空間折板桁架進行了靜力、動力、特征值屈曲及非線性屈曲分析，并研究了墻面空間折板桁架與屋面空間折板桁架的協(xié)調(diào)工作性能。結(jié)果表明，空間折板桁架結(jié)構(gòu)的工作性能雖不是很優(yōu)越，但考慮到屋面空間折板桁架與墻面空間折板桁架的協(xié)同工作，此類結(jié)構(gòu)具有較高的穩(wěn)定性。［關(guān)鍵詞］空間折板桁架; 特征值屈曲分析; 非線性屈曲分析中圖分類號：TU391 文獻標(biāo)識碼：A 文章編號：1002-848X(2015)15-0041-05
Structural design of spatial folded plate truss of Zhejiang Conservatory of Music gymnasiumXu Lingfeng, Xie Daoqing(Zhejiang Greentown Liuhe Architecture Design Co., Ltd., Hangzhou 310013, China)Abstract:The concrete frame-shear wall structure is applied as substructure in Zhejiang Conservatory of Music gymnasium, while the spatial folded plate truss structure is used as the steel superstructure considering the architectural function and campus overall style. In this structure, the roof and both sides of the wall are constructed of the spatial folded plate trusses, the vertical bars in the inner sides of the wall are buried effectively in the concrete walls or columns of the substructure, just as an accordion floating in the air from east to west. In order to guarantee the accuracy of analytical results, based on the whole model with the substructure and superstructure, the static, dynamic, characteristic value buckling and non-linear buckling properties of the spatial folded plate truss were analyzed. Besides, the coordinated performance between the spatial folded plate truss of the roof and the wall was also analyzed. The results show that the spatial folded plate truss structure performs not very well, but in consideration of the coordinated performance between the spatial folded plate of the roof and the wall, this kind of spatial folded plate structure can also provide good stability performance.Keywords:spatial folded plate truss; characteristic value buckling analysis; nonlinear buckling analysis
