［摘要］简要介绍了本次《混凝土结构设计规范》修订中对于安全问题的考虑，包括结构在天灾人祸偶然作用下的抗灾性能、结构的整体稳固性、结构设计中的安全层次。修订规范增加了“结构方案”的要求，加强了结构分析的内容，适当增加了构件设计中的安全储备，加强了结构构件的连接构造措施。由于采用高强、高性能材料以及技术进步的成果，在全面提高安全度的条件下，并未引起材料消耗的明显增加。

Abstract:Security issues considerations in the revision of Code for design of concrete structures are briefly introduced, such as calamity resistance performance of structure under the occasional act of natural and man-made disaster, the structural robustness and safety level in the  structure design.  With the code revision, structural concept requirement is increased, structural analysis is strengthened, the emergency capacity in the designing component is modestly expanded,  the connections-structural measures about structural element are also strengthened. Because of  the application of high-strength and high-performance materials and technological advance, the reliability improving has not increased the materials consumption obviously.

Keywords:concrete structure; structural safety; resilience performance; robustness
