The Health Monitoring of a Prestressed Concrete Beam Using Inverse Modeling Technique and Measured Dynamic Response
Abstract : This paper presents an inverse modeling technique using dynamic strain responses to identify the prestressed concrete beam parameters: the pretension in the cable and the prestress in the concrete. The direct problem corresponds to 2D elastodynamics equations. To get the beam parameters, we minimize a classical data misfit function using a gradient-like algorithm. A low-cost computation of the functional gradient is performed using the adjoint problem
