Paper Abstract

Two points source method was proposed for damage detection in concrete structures. To validate the proposed method, finite element simulations were carried out. In 3-D models, non-reflecting boundary conditions were considered to model an infinite medium so that the models prevented artificial dilatational stress wave reflections generated at the boundaries from reentering the model and contaminating the results. Then, two different types of damages (crack and deterioration) were introduced to investigate if the proposed method could detect the damages. From the finite element simulations, it is shown those damages are detectable and their severities can also be identifiable. Besides, the proposed method has shown that two points source method does not require any baseline signal for the damage detection; hence, its efficiency is verified.
