［摘要］新長沙火車站站臺鋼雨篷采用樹狀結(jié)構(gòu)的剛架體系。從整體受力體系的角度來設(shè)計(jì)樹狀結(jié)構(gòu)，進(jìn)而詳細(xì)分析其受力狀況；通過非線性屈曲分析，跟蹤加載的全過程，可知樹狀結(jié)構(gòu)具有較好的穩(wěn)定性和承載能力；采用有限元軟件對其中的關(guān)鍵節(jié)點(diǎn)進(jìn)行數(shù)值分析，結(jié)果表明節(jié)點(diǎn)具有較強(qiáng)的強(qiáng)度和剛度。整個結(jié)構(gòu)體系滿足規(guī)范要求。

Abstract:The platform roof of Changsha New Railway Station is made of rigid frame supported by tree structure. The tree structure should be regarded as a whole bearing structure, and detailed analysis was carried out. Then by using the non-linear buckle analysis, the whole loading process of the structure was tracked. Results prove that it has better stability and bearing capacity. At last, key nodes in tree structure were numerically analyzed with FEM software. Results show that the nodes are of enough strength and rigidity. The whole structure meets the regulation of codes.
Keywords:tree structure; whole bearing structure; buckle analysis; node analysis
