摘要
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。
The entrance structure of Yinan Industrial Park in Xinjiang was analyzed,the shape of which is unusual.Studies on influence of member internal force distribution from arc truss inner torque,release of temperature effect and impact on structure from horizontal and vertical earthquakes were made.By the comparison of the result of whole structural analysis and separate structural analysis for this structure under the action of earthquake and temperature,necessity of the whole structural analysis is proved to achieve real response of the structure and avoid the defect of the separate structural analysis,which can serve as a reference for other similar projects.
