As compared to design codes of practice in developed countries, the safetymargin of structural members set in the Chinese Building Code for Concrete Structures is rather low.
我国混凝土结构设计规范的安全设置水准与国际通用标准之间存在着相当大的差距。

According to the computed result , the structure of NEEC is safe , but its safetymargin is small, so the safety of the product should also be ensured through the design.
A vibration failure mode of structural system was presented according to engineering design criterion. The safetymargin equation of the vibration failure mode was developed.
