摘　　要：详细分析了某学校大门在温度荷载下的受力特性。并以简单模型为例,借助ANSYS有限元分析程序,详细地分析了拱结构在不同支座形式、不同跨度、不同矢跨比情况下,结构受力的变化,并将温度荷载下结构的受力情况和一般普通荷载进行了比较。分析表明,温度效应主要与约束形式和结构自身的刚度有关。对于大跨拱结构,尤其应该注意中间支座的影响。It is analyzed that the temperature effect of a college gate in detailFurthermore,taking a simple model as example and by means of ANSYS,it is also analyzed that the temperature effect of longspan archshaped structure with different supports,spans and shapes,and it is compared to the effect of general loadsIt shows that the temperature effect is mainly concerned with the style of support and the rigidity of structureFor the longspan archshaped structure,the effect of middle support should be especially noticed
