（悉地國(guó)際設(shè)計(jì)顧問(wèn)(深圳)有限公司，上海 200235 ）[摘要] 超長(zhǎng)結(jié)構(gòu)未設(shè)置伸縮縫或設(shè)縫間距超出規(guī)定限值時(shí)，由于溫差及混凝土收縮的作用效應(yīng)積累，會(huì)產(chǎn)生較大的約束應(yīng)力，此時(shí)需分析溫差效應(yīng)對(duì)結(jié)構(gòu)水平及豎向構(gòu)件的影響。利用有限元軟件MIDAS BUILDING,研究分析溫差效應(yīng)對(duì)具體超長(zhǎng)結(jié)構(gòu)的影響，為合理設(shè)計(jì)提供依據(jù)。[關(guān)鍵詞}超長(zhǎng)建筑;超長(zhǎng)結(jié)構(gòu);溫差效應(yīng);溫度應(yīng)力;有限元中圖分類號(hào)：TU375 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S1-0662-04Influence of temperature difference effect on super long multi-layer structureMiao Liuhua, Guo Rui, Xia Guanghong, Zou Wenbao, Yan Ping(CCDI Group,Shanghai 200235,China)Abstract: Super long structure without expansion joint or joints is higher than the specified limit, due to the temperature difference and shrinkage of concrete accumulation, will have great constraint stress, which need analyzing the effect of temperature difference on horizontal and vertical members of structure. Research and analysis of temperature difference effect on specific super long structure, providing the basis for rational design, with finite element softwareKeywords: super long building, super long structure, influence of temperature difference, temperature stress, finite element
