Abstract

Abstract in Undetermined
Pre-stressed concrete is used to increase the load capacity in many civil engineering structures. There is a need for non-destructive methods to estimate the potential loss of pre-stress in these structures. In this study we investigate the acoustoelastic effect on the natural resonance frequencies of a pre-stressed concrete beam. Measured resonant frequencies increase with increasing compressive stress. Results agree with predicted frequency shifts obtained from a non-linear finite element model based on Murnaghan's third order elastic theory.
