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作者簡介：丁朝輝，碩士，高級工程師，Email：zhhding@sina.com.參考文獻(xiàn)［1］ 丁朝輝，王曉哲，江歡成，等. 廣西北海北部灣一號項(xiàng)目A4板樓超限高層抗震設(shè)防專項(xiàng)審查送審資料［R］. 上海：上海江歡成建筑設(shè)計(jì)有限公司, 2009.［2］ JGJ 3-2002 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，2002.［3］ 劉冬柏，譚征. 拱殼結(jié)構(gòu)設(shè)計(jì)中幾個(gè)問題的討論［J］.中外建筑，2010（5）：74-76.［4］ 龍馭球，包世華. 結(jié)構(gòu)力學(xué)教程（上冊）［M］. 北京：高等教育出版社，1991.
