    Abstract

    Resonance monitoring is an established method for detecting deterioration in materials in accelerated aging tests Current ASTM practice monitors a single resonance. If more than one resonance is monitored it becomes possible to distinguish localized deterioration from general deterioration, to identify the specific locations of deterioration, and to recognize anticipated deterioration events. Data on location of deterioration is important in durability tests for assemblies where a distinction between materials failures and failures due to stress concentration is needed. Relations for the interpretation of changes in resonance as location of deterioration are developed. A laboratory study of condition monitoring by resonance in fatigue loading of a welded steel frame is reviewed. A potential application for resonance monitoring in building assemblies is outlined.
