工程系统的内涵、抗震设计与设防原则

Engineering systems: its connotation, Seismic design and Prevention principle

工程系统的抗震设防原则与抗震设计方法是工程防灾研究的重要组成部分。本文讨论了为实现工程系统的抗震设防所应进行的研究工作，提出了工程系统基于风险的抗震设计思想，并就工程系统抗震研究中的若干关键问题提出了研究建议．

Seismic prevention principle and seismic design method are important parts of engineering systems disaster researches. In this paper, a new seismic design idea named as 'risk based design'is proposed for general engineering systems. On the basis of this idea, some research aspects are discussed in principle. It is suggested that the seismic prevention principle and seismic design method of engineering systems should be included in new model seismic code of China.
