摘　　要：当建筑物较高时,由于施工过程中的累积效应,由温度作用产生的竖向构件间的变形差较大,此时须考虑结构的温度效应。广州新电视塔属超高层建筑,从施工阶段到建筑物投入使用,结构始终处于暴露状态,且该建筑物属异形结构。因此,温度效应将对该结构的施工、内力等造成严重影响。通过对广州新电视塔进行温度效应分析,表明了温度作用对该结构变形的影响十分显著。对整体结构的温度效应和施工过程的温度效应的分析结果进行对比,两者存在差异,应引起重视。对不同的温度工况进行了分析,得到了相应的一些规律,为以后类似建筑的施工提供参考。For high-rise buildings, deformation difference along the vertical members due to the cumulative temperature load is large. Then the temperature effect must be considered. Guangzhou New TV Tower is a high-rise structure. From the construction phase to its service, the structure is always exposed to harsh envi- ronment. As a special-shaped structure, temperature effects cause serious impact on the construction of the structure and induce internal forces. In this paper, the temperature effect analysis of Guangzhou New TV Tow- er shows that the structural deformation of temperature effect is significant. Analysis results of temperature effects on the overall structure and the temperature effects during construction process were compared. Atten- tions should be paid to the difference. Different temperature conditions of the structure were analyzed; some corresponding findings were gotten to provide references for the similar construction in the future.
