摘要: 三角咀產(chǎn)業(yè)園項(xiàng)目的塔樓與裙房之間通過跨度為 42m 的鋼桁架連廊相連. 鋼連廊與兩側(cè)主體結(jié)構(gòu)之間采用抗震支座形成柔性連接. 主要從支座選型、結(jié)構(gòu)靜力分析、抗連續(xù)倒塌分析、罕遇地震下的變形計(jì)算、樓蓋舒適度分析以及節(jié)點(diǎn)多尺度有限元分析等方面對(duì)鋼連廊進(jìn)行了設(shè)計(jì)與分析. 分析結(jié)果表明,該連廊的剛度、承載力以及支座變形均很好地滿足相關(guān)規(guī)范要求,此分析方法對(duì)其他類似鋼結(jié)構(gòu)連廊工程的設(shè)計(jì)有一定的參考價(jià)值.

關(guān)鍵詞: 鋼結(jié)構(gòu)連廊;柔性連接;支座選型;樓蓋舒適度分析;節(jié)點(diǎn)多尺度有限元分析

Abstract: The towers and podiums of Sanjiaozui Industrial Park project are connected by a steel truss corridor with span of42m. Flexible connection is formed between steel corridor and main structure by using isolation bearing. The design andanalysis of steel corridor were carried out from bearing selection, structural static analysis, progressive collapse resistanceanalysis, deformation calculation under rare earthquakes, floor comfort analysis and multi-scale finite element analysis ofjoints. The analysis results show that the stiffness, bearing capacity and bearing deformation of the corridor meet therequirements of relevant codes. The analysis method has certain reference value for the design of other similar steelstructure corridor projects.

Keywords:steel structure corridor;flexible connection;bearing selection;floor comfort analysis;multi-scale finite elementanalysis of joint
