基于曲率模态的预应力混凝土损伤定位

Prestressed Reinforced Concrete Damage Location Based on Curvature Mode

采用曲率模态对预应力钢筋混凝土梁构件的损伤定位进行了研究,采用有限元方法计算出结构的位移模态。根据得到的位移模态利用差分计算得到曲率模态曲线。数值计算结果表明,曲率模态曲线能够对结构损伤进行识别定位。

This paper studies the damage location of the prestressed reinforced concrete beam component by using the curvature mode, and calculates the displacement mode of structure by using the finite element method. Based on the achieved displacement mode and the differences, the curve of curvature mode can be calculated. The numerical calculation result shows that the curve of curvature mode can distinguish and locate the structure damage.
