Abstract

Abstract: The static measurements such as structure displacement and stress are important factors to do the safety assessment of bridge structure by the synthesized assessment method． As weight values of sections are depended on experts’judgment by giving grades or filling judgment matrix forms，this method has more subjectivity． The damage sensitivity degree of monitoring parameters at different sections of bridge is analyzed，and a damage sensitivity factor S of each monitoring section is constructed． And then the weight value is obtained by normalizing the weight eigenvectors composed by S． The proposed method effectively avoids the subjectivity of weight determination．

Key words: bridge engineering, weight value, damage sensitivity, synthesized assessment

摘要： 采用综合法进行桥梁结构安全状态评估时，结构的位移和应变等静态监测参量为评估的重要因素，其截面的权重取值通常采用专家评分或填写判断矩阵表法得到，此法主观成分较大。通过分析不同截面处的监测参量对结构损伤的敏感程度，构造了各个监测截面的损伤敏感因子 S，再将由 S 组成的权重特征向量归一化，得到监测截面的权重值，从而比较好地避免了权重确定的主观性。
