| 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。

| Abstract: | It is analyzed that the temperature effect of a college gate in detailFurthermore,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 loadsIt shows that the temperature effect is mainly concerned with the style of support and the rigidity of structureFor the long span arch shaped structure,the effect of middle support should be especially noticed |
