The health monitoring of a prestressed concrete beam using inverse modeling technique and measured dynamic response

Résumé

This paper presents an inverse modeling technique using dynamic strain responses to identify the prestressed concrete beam parameters: the tension in the cable and the prestress in the concrete. The direct problem correspond 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.
