［摘要］恒豐貴陽中心項目結(jié)構(gòu)的平面長度達414m，寬度達83～145m，尺寸超長，2層作為上部塔樓的嵌固端。詳細介紹了施工階段溫差、使用階段溫差、收縮當(dāng)量溫差在本項目中的取值計算，以及在考慮季節(jié)溫差和收縮效應(yīng)共同作用下各工況的樓板溫度應(yīng)力分析，結(jié)果顯示溫度應(yīng)力對超長結(jié)構(gòu)的影響顯著。根據(jù)溫度應(yīng)力分析的結(jié)果，除了對應(yīng)力較大區(qū)域按照計算配筋結(jié)果進行雙層雙向配筋加強外，針對施工以及構(gòu)造還提出了相應(yīng)的技術(shù)措施以減小溫差收縮效應(yīng)的影響。

Abstract:Hengfeng Guiyang Center has a super-long dimension with the plane length of 414m and width of 83~145m，the second floor of it could as the embedded end of the upper tower. The calculations of temperature difference in construction stage, temperature difference in use stage and shrinkage equivalent temperature difference in this project were introduced in detail. The floor temperature stress analysis under different working conditions was introduced considering seasonal temperature difference and shrinkage effect. The results show that temperature stress has a significant effect on super-long structure. According to the results of temperature stress analysis, besides the double-deck and two-way reinforcement according to the calculated reinforcement results in large stress areas, corresponding technical measures were also put forward for construction and construction to reduce the effect of temperature difference shrinkage.
Keywords:super-long structure; temperature difference effect; thermal stress analysis
