［摘要］杭州湖濱國(guó)際名品街塔樓工程改造范圍非常廣，結(jié)構(gòu)設(shè)計(jì)難度非常大。主要的改造內(nèi)容有：1）東塔的底部拆除兩層樓板，新加一層樓板；2）西塔的底部拆除三層樓板， 新加兩層樓板；3）兩塔通過(guò)新增的三層裙房和標(biāo)準(zhǔn)層連廊連為一體，形成了帶錯(cuò)層的連體結(jié)構(gòu)，結(jié)構(gòu)的體型發(fā)生了重大變化。從整體結(jié)構(gòu)出發(fā)，討論結(jié)構(gòu)體系的選擇。通過(guò)調(diào)整結(jié)構(gòu)布置來(lái)優(yōu)化各項(xiàng)抗震指標(biāo)，進(jìn)而深化局部構(gòu)件的加固和關(guān)鍵構(gòu)件的節(jié)點(diǎn)設(shè)計(jì)，并分析了這些構(gòu)件的優(yōu)缺點(diǎn)。

Abstract: The retrofit project of Hangzhou Hubin International Boutique Compound involved major transformation of the original structural system, which brought extreme difficulty to structural design. The major retrofit work includes: 1) two bottom floors of the east tower were demolished for the construction of a new floor; 2) three bottom floors of the west tower were demolished for the construction of two new floors; 3) the new floors of the two towers are connected by new built three-loor podium, and the original standard floors of the two towers are also connected by a series of sky-ridges. The two isolated towers are transformed into a connected structure with split levels, which makes the structural system has a great change. The structural design procedure is summarized for this project. The optimization of the overall structural system is presented, the strengthening of structural members are discussed as well as the design of key structural joints, and their characteristics are compared.

Keywords: retrofit and strengthening;structural system;connected structure;split evel structure;joint
