TY - GEN A1 - Luong, Thi Mai Hoa T1 - Non-destructive assessment of the actual state of stress in existing truss structures by vibration measurements N2 - Based on the state-of-the-art research and advances in dynamic testing methods in the past decades, the research project aims to develop a non-destructive methodology to determine the axial forces and real stress state in existing truss structures making use of the vibration signatures of the natural frequencies and mode shapes. Furthermore, it aims to estimate the joint rigidity of trusses as well as to design structural health monitoring schemes for the safety of existing truss-type structures.
