对新疆伊南工业园造型奇特的入口结构进行分析,研究了弧形桁架内扭矩对杆件内力分布的影响、温度效应的释放以及水平和竖向地震对结构的影响等问题,对比了结构各部分的单体分析与整体结构的整体分析在地震及温度作用下的反应,以确定地震及温度作用在结构中比较真实的效应,从而弥补各个部分单独计算及支座假定不合理所带来的不利影响,为此类结构的设计提供参考。 This paper analyzes the peculiar entrance structure of Inan Industrial Park in Xinjiang, studies the influence of the torsion moment inside the arch truss on the internal force distribution, the release of temperature effect and the influence of horizontal and vertical earthquakes on the structure. And the overall structure of the overall analysis of the response to earthquakes and temperature in order to determine the role of earthquakes and temperature in the structure of the more realistic effects to make up for each part of the calculation and bearing unreasonable assumptions caused by unfavorable Influence, provide reference for the design of such structure.
