A Fundamental Study on the Ultimate Pull-Out Strength of an Anchor Bolt in Concrete Structures using SPH



The anchorage zone of the concrete structure under pull-out loading is usually designed by the assumption that there are three possible failure modes such as the rupture of anchor bolt, cone failure of concrete, and bond failure between anchor bolts. In general, the design load is considered the smallest load of these failure mode assumptions. However, unexpected failure often occurs in the anchorage zone due to the complex failure or the change of failure condition. Therefore, it is important to develop the accurate evaluation method of load bearing capacity of the anchor bolt. In this study, we conducted an analytical study using Adaptive Smoothed Particle Hydrodynamics (ASPH) to simulate the failure process of the anchorage zone and discussed the effect of embedment depth of anchor bolts on the ultimate strength
