摘　　要：随着城市发展脚步的不断加快,在钢—混凝土混合结构的基础上,出现了一种新型的较为特殊的混合结构———钢筋混凝土筒体与钢网壳混合结构。钢网壳使得建筑造型美观,但同时又带来了诸多新的问题,其中之一就是日照的影响。本文应用ANSYS有限元软件,以嘉峪关气象塔为例,进行了考虑日照温差的理论计算分析。结果表明,日照温差对钢筋混凝土筒体侧移和钢网壳杆件内力有不同程度影响,可供类似工程参考。With the acceleration of urbanization,based on the steel concrete composite structure,a new type of structure named latticed shell-concrete composite structure is appeared.Latticed shell make the tower beautiful but also bring a lot of problems,one of them is influence of the sunshine temperature difference.In this paper a typical example for Jiayuguan weather tower are given,with the software of ANSYS the effects of the difference of temperature on this structure was analyzed.The results indicated that considering the sunshine temperature has much influence on sideway of concrete cylinder and stress of latticed shell,which can be used as references for similar works.
