Abstract: Many bridges were seriously damaged by the Pacific coast of Tohoku Earthquake in 2011. Especially, bridge restrainer systems on the concrete pier were failed due to the anchorage zone’s fracture. In general, it’s considered that anchor bolt embedded in concrete is designed based on static load and bolt’s fracture. In this paper, we conduct numerical simulations with 3D FEM to a complex phenomenon such as corn failure and bond failure. In order to estimate load-bearing capacity of anchorage zone properly, we proposed mechanical model based on hydrostatic pressure. Consequently, failure condition of anchorage zone under various boundary condition could be simulated well using our proposed mechanical model.
