A study was recently conducted to assess the technical feasibility of using stress wave nondestructive evaluation methods to locate decayed members in timber bridges. Stress wave nondestructive evaluation techniques were used to locate decayed components in several timber bridges in eastern Oregon. Various stress wave techniques were used to conduct an in-situ evaluation of stringers, decking, and compression members. Components suspected as having decay were identified and evaluated in a laboratory after dismantling. Both visual evaluation of the members and subsequent laboratory testing indicated that the stress wave techniques were able to locate decayed components with a high degree of accuracy.
