"浦宁之珠"电视塔设计中的温度影响分析与处理

对于空间结构的设计,温度作用往往是一个不可忽略的影响因素.在有些工程的设计中,由于结构整体性等因素的需要,无法采取降低温度影响的措施,往往会造成结构构件设计应力水平的整体提高,增加结构工程成本.一般情况下,可以采用设置温度缝等方式来释放或降低温度应力,水平方向的温度缝是常见的温度缝处理.介绍的"浦宁之珠"结构设计根据工程特点在竖直方向设置温度缝的做法,具有一定的特殊性.

Analysis of Temperature Influence in the Design of "Puningzhizhu" Tower

The temperature action is a factor that can not be neglected in the design of spacial structures.Sometimes,it is difficult to find a measure to reduce the influence of the temperature in the design taking into account the need of the whole of the structure or other reasons,which causes higher stress level in the structure and then increases the cost of the structure in the end.Usually,we can set temperature joint to release or reduce thermal stress,temperature joint in the horizontal direction of the structure is often used in projects.In the design of "Puningzhizhu" tower,temperature joint in the vertical direction of the tower is set and it is a special point of the project.
