The structure is irregular on many aspects, such as irregular torsion, big opening, large span canopy, uneven floor stiffness distribution, leaned column and etc. Some key techniques of design, such as countermeasures to solve the above problems, calculation and analysis methods, local anti floating measures in basement, weak connection design on floor with local big opening, temperature stress action for super long structure, design of large span and long cantilever members, stair component in frame structure and etc, were introduced.Keywords: frame structure; local anti floating measure; big opening; temperature stress; leaned column作者簡介:王嘯,碩士,高級工程師,一級注冊結(jié)構(gòu)工程師, Email: wangxiao@ippr.net參考文獻(xiàn)[1]陳蘋艷,王嘯,張震,等. 鄭州華潤大廈結(jié)構(gòu)設(shè)計[J]. 建筑結(jié)構(gòu),2013,43(3):72-76.[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 50010—2010混凝土結(jié)構(gòu)設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社, 2011.[4]陸道淵,陸益鳴,徐麟. 青島國際會展中心二期工程中的預(yù)應(yīng)力設(shè)計[J].建筑結(jié)構(gòu),2007,37(5):76-79.
