In case of large scale vertical opening in an irregular high-rise building, a natural shape arch-shell structure is used as an innovation. In addition to optimize the concrete structural performance, the original architectural idea was brought to realization. Reasonable computing methods and construction details were proposed in order to guarantee the safety of the building.Keywords: natural shape arch-shell; irregular high-rise building; opening in building; multi-tower structure作者简介:丁朝辉,硕士,高级工程师,Email:zhhding@sina.com.参考文献[1] 丁朝辉,王晓哲,江欢成,等. 广西北海北部湾一号项目A4板楼超限高层抗震设防专项审查送审资料[R]. 上海:上海江欢成建筑设计有限公司, 2009.[2] JGJ 3-2002 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,2002.[3] 刘冬柏,谭征. 拱壳结构设计中几个问题的讨论[J].中外建筑,2010(5):74-76.[4] 龙驭球,包世华. 结构力学教程(上册)[M]. 北京:高等教育出版社,1991.
