邱倉虎,劉建平,張宇華,謝詩溶,杜文博(中國建筑科學(xué)研究院建筑設(shè)計院,北京 100013)[摘要]針對超高層建筑結(jié)構(gòu)設(shè)計實踐,探討、思考了嵌固部位確定時,SRC柱中型鋼柱的埋置部位、現(xiàn)澆混凝土空心樓蓋在超高層建筑結(jié)構(gòu)樓蓋系統(tǒng)中能否使用及如何采用、重力二階效應(yīng)中是否考慮高層建筑基礎(chǔ)整體傾斜值對穩(wěn)定性的影響三個問題。[關(guān)鍵詞]超高層建筑;SRC柱;埋置深度;空心樓板;整體傾斜中圖分類號:TU973文獻(xiàn)標(biāo)識碼:A文章編號:1002-848X(2012)07-0022-05Practice and think of several issues in structure design of skyscraperQiu Canghu, Liu Jianping, Zhang Yuhua, Xie Shirong, Du Wenbo(China Academy of Building Structure, Beijing 100013, China)Abstract: Three issues in structure design of skyscraper were discussed. Three issues are as follows: The imbedding position of steel bone in the column when the build-in position is determined; Whether the hollow floor system can be applied in the skyscraper and how to apply; Whether to consider the entire base inclination when determining the building stability influenced by the-gravity second-order effect.Keywords: skyscraper; SRC column; embedding depth; hollow floor; entire inclination作者簡介:邱倉虎,教授級高級工程師,一級注冊結(jié)構(gòu)工程師。參考文獻(xiàn)[1]GB 50011—2010建筑抗震設(shè)計規(guī)范[S]北京:中國建筑工業(yè)出版社,2010.[2]JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]北京:中國建筑工業(yè)出版社,2011.[3]GB 50007—2011建筑地基基礎(chǔ)設(shè)計規(guī)范[S].北京:中國建筑工業(yè)出版社,2011.[4]程志輝,張俊勝.帶地下室高層結(jié)構(gòu)的動力計算模型[J].華南理工大學(xué)學(xué)報,2005(6):12-15.[5]CECS 175:2004現(xiàn)澆混凝土空心樓蓋結(jié)構(gòu)技術(shù)規(guī)程[S].北京:中國計劃出版社,2004.
