（中國航空工業(yè)規(guī)劃設計研究院，北京 100120）[摘要] 國內(nèi)對于超長結(jié)構的溫度應力已做了很多研究，但對于超長開口環(huán)形平面結(jié)構確很少有實例參考。本文則以實際工程為例，分析開口環(huán)形超長結(jié)構的溫度效應，從變形規(guī)律、內(nèi)力、徐變、溫度縫設置等多個角度進行闡述，并找出規(guī)律。同時對不同結(jié)構進行經(jīng)濟性比較，得出相應結(jié)論。對類似工程有較高的參考價值。[關鍵詞] 開口環(huán)形結(jié)構;樓板溫度變形;溫度應力;經(jīng)濟性中圖分類號：TU119.22 文獻標識碼：A 文章編號：1002-848X(2013)S1-0672-05The analysis of temperature effect of opening annular plane structureJin Laijian, Jing Hui, Xie Jun, Wang Degang(Abstract: A lot of research about the temperature effect of long structure have been done up to now. However, the researches about extra-long opening annular structure are not enough. Thus, the temperature effect of the opening-annular-long structure was analyzed in this article, and corresponding conclusions were drawn. At the same time, an economical comparison of different structures based on temperature effect was also explained and analyzed. The conclusion we got have a high reference value for similar projects.Keywords: Opening annular structure; Temperature deformation of slab; Temperature stress; Economical efficiency作者簡介：景輝，碩士，一級注冊結(jié)構工程師，Email: lojhve@126.com。
