(中國(guó)建筑設(shè)計(jì)研究院 北京 100044)
【提要】 北京南銀大廈是一棟多功能高層建筑。根據(jù)工程場(chǎng)地情況，基礎(chǔ)采用預(yù)應(yīng)力混凝土管樁，計(jì)算沉降量滿(mǎn)足要求。上部抗側(cè)力體系采用框架筒體結(jié)構(gòu)，采取相應(yīng)的措施，解決了框架布置不規(guī)則、柱距大等工程設(shè)計(jì)中的難點(diǎn)。結(jié)構(gòu)計(jì)算分析結(jié)果表明，變形和承載力都滿(mǎn)足要求。結(jié)構(gòu)上部設(shè)置3層鋼框架，介紹了結(jié)構(gòu)的主要技術(shù)與構(gòu)造措施和鋼框架的設(shè)計(jì)情況。

Structural Design of Beijing Nanyin Mansion/Wang Huiying,Zhang Ning,Ge Hongtong(China Architecture Design and Research Group,Beijing 100044,China)
Abstract:The Beijing Nanyin mansion is a highrise building with multiple functions.The prestressed RC pipe pile is used in foundation design according to the ground condition,and the calculation settlement satisfies the requirement.The frametube system is adopted in the upper structure.Some measures are applied to deal with the difficult problems such as irregular arrangement of frame and large space between columns.The analysis results of the structure show that the deformation and bearing capacity satisfy the demand3floor steel frame is set at the top of the structure.The main techniques and construction measures of the structure and the design of steel frame are presented.
Keywords:prestress RC pipe pile；frametube; steel frame; foundation design; joint design
