Application and Verification of EDLT for Damage Detection

초록

An elastic damage load theorem was derived and verified to enhance the efficiency of damage detection in flexural structures using the static displacement changes due to damages. 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 sensors. From numerical and experimental application of the elastic damage load theorem to damage identification, it can be concluded that the elastic damage load theorem may be useful in the long term health monitoring and the damage assessment using periodical static loading test.
