Abstract: With regard to the dynamic problem in the anchor engineering, a destructive experiment using harmonic seismic waves is designed to analyze anchorage mechanism, shear stress distribution and dynamic pull-out resistence under dymanic load. The results show that the shear stress under dynamic action becomes stronger from the top end to the bottom end of the anchor bolt and play its role along the whole anchor bolt. The pull-out resistence under dynamic action is stronger than the experimental simulation under static situation and experiment.
