考虑温度影响的桥梁结构损伤识别
Structural damage identification including the temperature difference based on response sensitivity analysis
摘要
Abstract
Damage detection based on a reference set of measured data usually has the problem of differ-ent environmental temperature in the two sets of measurements,and the effect of temperature difference is usually ignored in the subsequent model updating.It attempts to identify the structural damage including the temperature difference both local damages,and the temperature difference are identified in a gradient-based model updating method based on dynamic response sensitivity.The measured dynamic responses of the structure from two different states are used directly to identify the structural local damages and the temperature difference.A planar truss structure are studied to illustrate the effectiveness of the proposed method.关键词
