［摘要］广州新客站屋顶为大跨度钢结构，温度作用是结构设计的控制因素之一。采用Ecotect软件，研究了广州新客站各时刻不均匀温度的分布。利用MIDAS软件，分析了不均匀温度作用对屋顶结构的影响，并与整体均匀升温作用对结构的影响进行了对比。结果表明，整体均匀升温并非结构设计的最不利工况，结构设计需要考虑不均匀温度作用的影响。

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
