（中國(guó)航空工業(yè)規(guī)劃設(shè)計(jì)研究院，北京 100120）[摘要] 國(guó)內(nèi)對(duì)于超長(zhǎng)結(jié)構(gòu)的溫度應(yīng)力已做了很多研究，但對(duì)于超長(zhǎng)開口環(huán)形平面結(jié)構(gòu)確很少有實(shí)例參考。本文則以實(shí)際工程為例，分析開口環(huán)形超長(zhǎng)結(jié)構(gòu)的溫度效應(yīng)，從變形規(guī)律、內(nèi)力、徐變、溫度縫設(shè)置等多個(gè)角度進(jìn)行闡述，并找出規(guī)律。同時(shí)對(duì)不同結(jié)構(gòu)進(jìn)行經(jīng)濟(jì)性比較，得出相應(yīng)結(jié)論。對(duì)類似工程有較高的參考價(jià)值。[關(guān)鍵詞] 開口環(huán)形結(jié)構(gòu);樓板溫度變形;溫度應(yīng)力;經(jīng)濟(jì)性中圖分類號(hào)：TU119.22 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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(jiǎn)介：景輝，碩士，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email: lojhve@126.com。
