Experimental Evaluation of Proposed Precast RCS Connection under Cyclic Loading

In this paper, test results of two half-scale interior precast Reinforced Concrete column to Steel beam (RCS)connections with proposed joint configurations with and without shear keys in the joint are presented. Proposedconnections consisted of steel beams were connected to the precast column, using extended face bearing plates,embedded in the connection zone. Two samples were loaded under reversed displacement controlled condition. Thefailure mode, joint distortion, lateral load capacity, stiffness retention, stiffness degradation were evaluated. Presenceof shear keys in the joint enhances strength and stiffness of connection and reduces joint distortion.
