TY - GEN A1 - Luong, Thi Mai Hoa T1 - Identification of the state of stress in iron and steel truss structures by vibration–based experiments N2 - Precise identification of the axial forces and corresponding stresses plays a crucial role for the preservation of existing truss structures. The assessment measures require non–destructiveness, minimum intervention and practical applicability. The work aims to develop a non–destructive methodology to identify the axial forces and stress states in iron and steel truss structures based on vibration measurements and the finite element model updating coupled with optimization techniques.
