摘　　要：沈阳严寒地区季节温度差异大,降温工况使混凝土结构产生较大拉应力,本文采用MIDAS Gen软件对中海和平之门3^(#)地商业项目超长混凝土结构进行温度荷载作用分析,按工程的实际情况施加温度荷载,得到该工程在最不利荷载工况下的温度分析结果,并对结构薄弱部位采取加强措施。分析结果表明,一层位置温度应力最大,温度应力分别向高楼层位置和地下室部位递减,在下沉式庭院结构刚度突变位置的温度应力较大。In view of the large seasonal temperature difference in the cold and cold areas of Shenyang, the cooling conditions make the concrete structure have a greater tensile stress, in this article, MIDAS Gen software is used to analyze the temperature load of the ultra-long concrete structure of the commercial project of Zhonghai Peace Gate 3^(#), the temperature loads are applied according to the actual situation of the project, the temperature analysis results of the project under the most unfavorable load conditions are obtained, and strengthening measures are taken for the weak parts of the structure.The results show that, the temperature stress at the first floor is the largest, the temperature stress decreases toward the high-floor location and the basement location, the temperature stress at the location of the sudden change of the rigidity of the sinking courtyard structure is large.

关 键 词：超长混凝土结构 温度应力 降温工况 刚度突变
