超长结构温度应力分析方法与控制措施

Analysis Method and Control of Temperature Stress in Super-long Structure

许多超长的大型公共建筑结构不断出现,如果按照规范要求需设置一道或多道伸缩缝,会带来诸多不便。因此,常常出现超长结构不设或少设伸缩缝的情况,这就需要对未设伸缩缝的超长结构在温度作用下进行计算分析和采取控制措施进行处理。系统介绍了几种超长结构温度应力分析方法,详细描述了对超长结构温度应力的控制措施。由于超长结构温度分析与控制是一个相当复杂的问题,归纳总结了需进一步研究的问题。

Many large public buildings long structure is emerging,according to the specifications required to set up a multi-channel expansion joints,will bring a lot of inconvenience.Therefore,there is often super-long structure without expansion joints or less set the case,which requires temperature calculation and analysis and control measures for long structure without expansion joints.Several long structure thermal stress analysis are introduced,some control measures for the long thermal stress are descript in detailed.As long structure temperature analysis and control is a very complex issue,the need for further research is pointed out.
