摘 要: 采用新进提出的结构损伤识别分析方法,称为自适应方法,对钢筋混凝土三跨连续梁桥试验模型展开损伤识别研究。首先建立桥梁的有限元模型,然后进行模型试验,在测量信息有限的条件下通过自适应方法识别该桥梁结构的参数及损伤,验证了所提出的自适应损伤识别方法的准确性和有效性。
关 键 词: 工程结构;桥梁工程;结构健康监测;自适应方法;结构损伤识别

Abstract: In this paper, a newly proposed data analysis method for structural damage identifications, referred to as the adaptive approach, was studied using a continuous beam bridge structure. The finite element model of the bridge was established and experimental study was carried out with limited number of measured response data. The acuracy and capability of the proposed approach in identifying the structural damage is verified.
Key words: engineering structures; bridge engineering; structural health monitoring; adaptive approach; damage identification of structures
