基于位移的设计是一种在设计中以位移要求为前提的抗震设计方法 ,因此直接与结构的破坏有关。本文对桥梁结构基于位移的抗震设计方法的国外的研究进行了回顾 ,并指出该设计方法用于工程实践时应该注意的几个问题。
The displacement-based design is a seismic design method that takes displacement requirements as a precondition in the design and is therefore directly related to the structural damage. This paper reviews the overseas research on the displacement-based seismic design method of bridge structure and points out some issues that should be noticed when this design method is applied in engineering practice.
