［摘要］简述了混凝土结构抗震设计的概念、特点以及本次规范修订内容的调整。抗震设计包括确定结构方案、地震作用以及构件的抗震设计，本规范反映后一部分内容。抗震设计强调概念设计，在静力设计的基础上，按抗震等级提出要求，并考虑构件抗震破坏的特点进行承载力设计, 避免剪切、压溃等引起的非延性破坏；并通过截面控制条件、承载力计算系数调整及配筋构造等措施得以落实。本文介绍了材料、梁、柱、墙、预应力构件等的抗震设计要求。

Abstract:The concept and characteristic of seismic design of concrete structure as well as the adjustment of new building code are summarized. Seismic design concludes structure plan, earthquake action and structure member design. The last part is reflected in this code. In seismic design, the concept design is emphasized. According to the anti-seismic grade, based on the static design, the load capacity design of structure must consider the characteristic of seismic failure of members, preventing the non-ductile failure such as shear failure and collapse. That could be controlled by restricting the section condition of member, adjustment by load capacity coefficient and construction measures. The seismic design requirements to the material, beams, columns, walls and prestressed members are introduced.
Keywords:concrete structure; seismic design
