摘要
从适用范围、膨胀节的结构形式及设计准则等方面对美国、日本及我国的膨胀节标准进行综述和对比。结果发现 ,由于未考虑薄膜应力及初始角位移对失稳压力的影响 ,我国标准给出的极限设计压力偏高 。
The standards of the expansion joints of the USA,Japan, and the P.R.China were described and compared in application range, structure, and design. It was found that the limit design pressure determined by the standard of the P.R.China was some high and not very reliable because of neglecting the influences of film stress and initial angular displacements on the unstable pressure.
