摘要: A system identification technique based on the static displacement changes due to damages is proposed to enhance the efficiency of damage detection in flexural structures. For this, an elastic damage load theorem was derived and verified. Comparisons with numerical and experimental tests were performed to investigate the applicability and advantage of the proposed theorem. In addition, it is shown that the sparse measurement can be overcome by increasing the loading conditions instead of increasing the number of measurement …
