[摘要] 招商銀行上海大廈由南北兩個(gè)塔樓和塔樓間的大跨度連橋組成，均屬于平面和豎向均不規(guī)則的抗震超限建筑。本文介紹了對(duì)該結(jié)構(gòu)進(jìn)行1:25縮尺模型的模擬振動(dòng)臺(tái)試驗(yàn)。對(duì)試驗(yàn)結(jié)果的分析表明：招商銀行上海大廈的南塔樓、北塔樓結(jié)構(gòu)均可以滿(mǎn)足的三水準(zhǔn)抗震設(shè)防要求，連橋結(jié)構(gòu)在滿(mǎn)足三水準(zhǔn)抗震設(shè)防要求的前提下，可以滿(mǎn)足中震時(shí)節(jié)點(diǎn)處于彈性受力狀態(tài)，大震不屈服的設(shè)計(jì)目標(biāo)。此外，還證實(shí)了連橋鋼桁架與混凝土簡(jiǎn)體連接節(jié)點(diǎn)是連橋結(jié)構(gòu)的薄弱部位。

Abstract: China Merchants Bank Shanghai Building is composed of the North and the South Tower, a large-span link-bridge between the two towers. The configuration of the horizontal and vertical plan does not satisfy the rules of the seismic code. This article gives a introduction to the shaking table test of a 1:25 scale model. The results of the test shows that the behavour of the north tower structure. south tower structure and the link-bridge structure can meet the requirement of the three-level seismic-resisting design. And the link-bridge structure can also remain elastic node under medium-level earthquake, does not yield under rare-level earthquake. In addition, the test shows that the joint of the link-bridge and the concrete tube is the weakest part of the link-bridge structure.
Keywords: high-level mixed structure; large-span link-bridge structures; shaking table test
