An evaluation of shear design criteria by numerical analysis for cast-in-place anchor

Numerical analysis is carried out to identify the appropriateness of the design codes that is available for the shear design of fastening system at Nuclear Power Plant (NPP) in this study. This study is intended for the cast-in-place anchor that is widely used for the fastening of equipment in Korean NPPs. The microplane model and the elastic-perfectly plastic model are employed for the quasi-brittle material like concrete and for the ductile material like anchor bolt as constitutive model for numerical analysis and smeared crack model is employed for the crack and damage phenomena. The developed numerical model is verified on a basis of the various test data of cast-in-place anchor. The appropriateness of both ACI 349 Code and CEB-FIP Code is evaluated for the shear design of cast-in-place anchor through the numerical analysis considering the analytical variables like effective embedment depth, diameter of anchor bolt and edge distance
