Most of systems and components in nuclear power plants (NPPs) are anchored to the concrete structure and other components by means of post installed anchors. In order to develop more accurate seismic analysis model of equipment in NPPs, a deep consideration of concrete-anchor connection behavior is required. In this paper, the nonlinear finite element analysis was conducted for the concrete-anchor connection zone details. From the analysis results including strength and load-displacement relation was derived according to design variables including geometry and material properties.
