[摘要]  以彈塑性時(shí)程分析方法為基本手段，對(duì)上海國(guó)際金融中心三塔樓之間的T字形大跨度連廊結(jié)構(gòu)進(jìn)行了分析研究，在評(píng)價(jià)其自身抗震性能的基礎(chǔ)上，重點(diǎn)研究了連廊與主塔樓之間在大震下可能出現(xiàn)的相互碰撞以及撞擊力的大?。淮送?，還研究了設(shè)置于連廊中的鋼板剪力墻的屈曲問題。分析結(jié)果表明，罕遇地震下，連廊本身性能滿足預(yù)期目標(biāo)，連廊與主塔之間的撞擊力小于設(shè)計(jì)水平，在考慮鋼板剪力墻屈曲的不利影響后，連廊仍然能滿足安全要求。所采用的分析研究方法對(duì)其他類似復(fù)雜連廊結(jié)構(gòu)的設(shè)計(jì)和分析具有較好的借鑒意義。

Abstract: The elastic-plastic time-history analysis was carried out to a “T” shaped long-span corridor structure between the three towers of Shanghai International Financial Center. On the basis of seismic performance evaluation, this paper studies the mutual collision and the magnitude of the impact force between the corridor and the main towers during severe earthquake. In addition, the buckling problem of steel plate shear walls in the corridor is investigated. The analysis results show that, during severe earthquakes, the corridor’s performance meets the expected demands and the magnitude of the impact force is less than the design level. Besides, the corridor itself still meets the safety requirements considering the adverse effects of steel plate shear walls’ buckling. The analysis research methods in this paper can be significantly referenced to other similar complex corridor structures.
Keywords: long-span corridor; seismic performance; collision; steel plate shear wall; buckling
