Abstract: 

Structural joints in precast concrete structures have a determinant role in strength, stability and reliability of such structures. Therefore it is necessary to investigate their behavior under various loading conditions. In this paper, numerous models of structural joints with different shapes and number of shear keys are selected and analyzed using finite element method and the results are compared to some experimental works and results obtained from codes of practices. Also, the effects of depth and number of shear keys on the reduction of shear stress in this type of joints are studied.
