英文摘要：

With the development of sensor technologies, signal acquiring and processing technologies, and system modeling technologies, structural health monitoring and damage detection using dynamic responses has got considerable attention. The purpose of this paper is to present an overview of vibration-based damage detection methods developed over the last 20 years and their applications. For each kind of method, their strengths and limitations are discussed. Finally, for damage detection of civil engineering structures, some topics which are worth studying further are proposed.
