邱仓虎,刘建平,张宇华,谢诗溶,杜文博(中国建筑科学研究院建筑设计院,北京 100013)[摘要]针对超高层建筑结构设计实践,探讨、思考了嵌固部位确定时,SRC柱中型钢柱的埋置部位、现浇混凝土空心楼盖在超高层建筑结构楼盖系统中能否使用及如何采用、重力二阶效应中是否考虑高层建筑基础整体倾斜值对稳定性的影响三个问题。[关键词]超高层建筑;SRC柱;埋置深度;空心楼板;整体倾斜中图分类号:TU973文献标识码:A文章编号: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作者简介:邱仓虎,教授级高级工程师,一级注册结构工程师。参考文献[1]GB 50011—2010建筑抗震设计规范[S]北京:中国建筑工业出版社,2010.[2]JGJ 3—2010高层建筑混凝土结构技术规程[S]北京:中国建筑工业出版社,2011.[3]GB 50007—2011建筑地基基础设计规范[S].北京:中国建筑工业出版社,2011.[4]程志辉,张俊胜.带地下室高层结构的动力计算模型[J].华南理工大学学报,2005(6):12-15.[5]CECS 175:2004现浇混凝土空心楼盖结构技术规程[S].北京:中国计划出版社,2004.
