Abstract

Average strain of cell of certain length can be measured by long-gauge Fiber Bragg Grating sensors. This article, taking average flexural rigidity of cell ^EI̅ based on average strain of cell and wide average height of neutral axis of cell ^Z̅ as damage identification parameters, validates via multiple damage numerical simulation of I-shaped cantilever steel beams and simple-supported steel beams, and proves that structural static multiple damage identification method based on average strain of cell is feasible.
