考虑抗弯刚度不确定性的简支梁桥损伤定位方法 = Damage localization method for simply supported bridge with flexural stiffness uncertainty considered
为了处理主梁抗弯刚度的不确定性,实现简支梁桥主梁的准确损伤定位!通过进行影响线分 析!基于位移影响线二次差值的概念提出了一个损伤定位指标----跨中位移影响线差值指标(DIILMSD), 通过测量移动荷载下主梁跨中的竖向位移增量即可基于DIILMSD指标建立相应的损伤定位方法。研究结果表明:对于局部抗弯刚度具有不确定性的实际主梁,其损伤位置可通过对比损伤前后的DIILMSD数据图形来进行有效的识别,如果某一点(x2=x'+m)和邻近!个点连线的斜 率发生了变化!则说明损伤出现在区间[x',x'+m]或[l- x'- m,l- x' (之内)损伤...
