Dynamic Characterization of Posttensioned Rods in Stressed Timber Systems

Chen, H. L. / Venkatesh, G. / Gangarao, H. V. S. / Stephens, J. E.

Abstract An analytical and experimental approach is presented to monitor the tension levels in posttensioned high strength rods of stressed timber systems. The response of rods under an impact load is characterized and then correlated with tension in the rod. This approach is simpler and faster than the existing techniques and is intended for use during routine structural inspection. The dominant frequency of the rod has distinguishable variation for varying tension levels.
