| 摘 要： | 结合南京新城大厦工程，利用有限元软件对超长混凝土结构收缩和温差引起的内力进行模拟，得出了温降作用下结构内部温度应力的大小及其分布规律，对超长结构的温度作用进行了探讨，并提出无粘结预应力钢筋抵抗温度应力的方法以及施工设计中常见问题的解决方法，可为类似工程提供参考。

| Abstract: | According to the project of nanjing xingcheng building, The temperature stress was analyzed with finite element analysis method, and the rules of the thermal stress distribution were given. The thermal stress of over-long con- crete structure was approached. A design method about temperature stress of unbonded prestress was used, the method of construction design was given. All of these can offer reference for similar project. |
