  • An analytical study on the effect of pull-out speed of anchor bolts on pull-out strength and failure patterns

説明

<p>The pull-out strength of anchor bolt embedded in concrete is usually estimated by assuming that the stress is uniformly generated on the failure surface. However, it is known that when anchor bolts are subjected to a sudden pull-out load, the stress distribution becomes non-uniform and the load carrying capacity also differs from that under static loading. In this study, the embedment depth and pull-out velocity of bonded anchors were taken as parameters, and their effects on the failure mode and load carrying capacity were investigated based on numerical analysis using the SPH method. As a result, it was confirmed that the failure mode changes from cone fracture to combined fracture, in which cone fracture and adhesion fracture are mixed, as the pull-out speed increases.</p>
