| 摘 要： | 文章探讨了传统的基于结构抗力的抗震设计方法,分析了位移在桥梁结构的强震破坏中的重要影响。结合强度设计和位移控制的两阶段抗震设计的思路,提出了高架桥梁桥墩抗震设计首先是防止结构的脆性破坏,再控制结构的塑性破坏。这种用位移进行结构的抗震设计将更经济合理。

| Abstract: | With discussion on conventional aseismic design method based on structural resistance, and analysis on great impact of displacement in macroseismic destruction of bridge structure, a new method of aseismic design for piers of elevated bridge is proposed for reference, combining with the Two-Stage aseismic design of strength design and displacement control. |
