The objective of this paper is to verify the effect of embedded depth and width of head to the tensile capacity of head reinforcement embedded in concrete. FEM(Finite Element Method) analysis is conducted by using ADINA program (version 8.4) for the embedded reinforcement. Main variables in the analysis are embedded depth and width of head. Analysis result showed that the stiffness and strength depended on the embedded depth of head reinforcement. However, the increment of stiffness and strength were not high even if the width of head increased. On the other hand, flexural deformation occurred at the head when the width of head was increased.
