A vibration failure mode of structural system was presented according to engineering design criterion. The safety margin equation of the vibration failure mode was developed.
从工程上常用的振动设计准则出发，定义了振动问题的破坏模式，给出了以结构自振频率和外载频率为基本随机变量的安全边界方程。
It is found that the first vibration mode is vertical by the dynamic analysis and the structural response are in the al...
通过动力分析可以发现，结构的第一振型为竖向振动，动力分析结果也满足抗震要求，说明结构形式是合理可行的。
