［摘要］廣州新客站屋頂為大跨度鋼結(jié)構(gòu)，溫度作用是結(jié)構(gòu)設(shè)計的控制因素之一。采用Ecotect軟件，研究了廣州新客站各時刻不均勻溫度的分布。利用MIDAS軟件，分析了不均勻溫度作用對屋頂結(jié)構(gòu)的影響，并與整體均勻升溫作用對結(jié)構(gòu)的影響進(jìn)行了對比。結(jié)果表明，整體均勻升溫并非結(jié)構(gòu)設(shè)計的最不利工況，結(jié)構(gòu)設(shè)計需要考慮不均勻溫度作用的影響。

Abstract:The roof structure of New Guangzhou Railway Station is a large-span structure, and the temperature action is one of controlling factors. Using software Ecotect, the distribution of non-uniform temperature is studied. Using software MIDAS, the influences of non-uniform temperature action are analyzed, and compared with those of uniform temperature action. The results show that uniform temperature action is not the most adverse combination, and the non-uniform temperature action should be considered for the structural design.

Keywords:New Guangzhou Railway Station; steel structures; non-uniform temperature; temperature action
