摘要
温度作用是超长结构设计中需要解决的主要问题，本文通过对某工程弧形超长的混凝土结构与钢结构的温度作用进行了分析，与矩形超长结构进行了对比，验证了弧形体型有利于释放温度应力。同时提出了有反弯点的连续弧形结构的等效温度区段长度的计算方法，以供类似工程参考。
Temperature action is the key problem requiring to be solved in designing super-long structures. We analysed the temperature action in a curved concrete building and a curved steel building ,and then compared the rusuhs with regular rectangular structures, it is proofed that the curved form is advantaged in releasing the temperature stress. Also we gived the equivalent temperature section length of the continuous curved structure with inflection point, that can be referenced in similar sturcture
