A multiplicative regularized Gauss-Newton method with trust region Sequential Quadratic Programming for structural model updating

•A new method for sensitivity-based model updating is proposed.•Ill-conditioning is mitigated by a multiplicative regularization approach.•A trust region Sequential Quadratic Programming with bound constraints is used.•The size of the trust region is a parameter of the regularization functional.•The...
