（北京市建筑設(shè)計研究院 北京 100045）
【提要】北京天亞花園工程為高級商住公寓樓，地上30層，建筑總高度9565m，采用鋼筋混凝土框支剪力墻結(jié)構(gòu)體系，為超限高層建筑。工程設(shè)計從概念設(shè)計入手，采用多種程序進行結(jié)構(gòu)彈性有限元分析、結(jié)構(gòu)彈塑性時程分析及靜力推覆分析。針對薄弱層、薄弱部位采取設(shè)置型鋼等加強措施，以滿足抗震設(shè)防要求。探討了此類超限高層建筑的設(shè)計方法和構(gòu)造措施。
【關(guān)鍵詞】 彈塑性分析 超限高層建筑 框支剪力墻 轉(zhuǎn)換層 有限元分析
Research on Design of Shear Wall Supported by Frame System in Beijing Tianya Garden/Xu Bin, Miao Qisong, Wang Yuexian, Qi Wuhui(Beijing Institute of Architectural Design,Beijing 100045,China)
Abstract:Beijing Tianya Garden is a highrise apartments building, with 30 storey and 9565 meters high on the ground The reinforced concrete shear wall supported by frame structure is used It is outofcodes of Chinise for highrise building in the earthquake fortification zone of 8 degree The structure design and construction measures are introduced for this building. The finite element analysis and the elasticplastic analysis are used. The design method and construction measures are discussed,which can be referred to similar buildings.
Keywords:elasticplastic analysis; outofcodes; highrise buildings; shear wall supported by frame; transfer floor; finite element analysis; structure design
