［摘要］對(duì)新疆伊南工業(yè)園造型奇特的入口結(jié)構(gòu)進(jìn)行分析，研究了弧形桁架內(nèi)扭矩對(duì)桿件內(nèi)力分布的影響、溫度效應(yīng)的釋放以及水平和豎向地震對(duì)結(jié)構(gòu)的影響等問(wèn)題，對(duì)比了結(jié)構(gòu)各部分的單體分析與整體結(jié)構(gòu)的整體分析在地震及溫度作用下的反應(yīng)，以確定地震及溫度作用在結(jié)構(gòu)中比較真實(shí)的效應(yīng)，從而彌補(bǔ)各個(gè)部分單獨(dú)計(jì)算及支座假定不合理所帶來(lái)的不利影響，為此類結(jié)構(gòu)的設(shè)計(jì)提供參考。

Abstract: 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.

Keywords: arc truss; spatial structure; whole structural analysis; separate structural analysis
