［摘要］兩辦公樓在標(biāo)高89.9m處通過空中花園走廊相互連接，結(jié)構(gòu)方案采用左右塔樓分別伸出懸臂桁架的方式實(shí)現(xiàn)，通過懸臂桁架與辦公樓整體建模計(jì)算，分析了小震、中震、大震下結(jié)構(gòu)整體受力狀況，使懸臂桁架在不同地震和荷載組合情況下均滿足了設(shè)計(jì)控制指標(biāo)。對懸臂桁架的關(guān)鍵節(jié)點(diǎn)進(jìn)行了構(gòu)造設(shè)計(jì)和有限元分析，對懸臂根部的樓板進(jìn)行了應(yīng)力分析和構(gòu)造加強(qiáng)。

Abstract: Two office buildings were connected by an air corridor at the 89.9m elevation. Two mirrored cantilever truss structures were adopted for the air corridor connecting to the buildings. Complete structure model was formed, force conditions in frequent occurred earthquake, the design earthquake, rarely occurred earthquake were analyzed, setting target for cantilever truss is achieved in different seism and various loading combinations. Key nodes of the cantilever truss were designed and analyzed. Stress of the floor was analyzed and the construction measures were adopted.
Keywords: cantilever truss; stress ratio; finite element analysis
