Abstract : This paper presents an experimental investigation of the structural behavior of bolted semi-rigid beam-column connections. Three specimens with different connection parameters were created and tested under various loads up to failure. The main variables considered in the experimental test were the end-plate thickness and bolt diameter. The experimental results were used to obtain the moment-rotation (M-ϕ) relationships for the tested connections, from which the connection stiffness, rotation capacity, and ultimate moment resistance were evaluated. The failure modes of the tested connections were observed and documented, showing that the connection behavior was mainly governed by end-plate deformation and bolt response. The results indicate that variations in end-plate thickness and bolt diameter significantly influence the stiffness and moment capacity of semi-rigid connections.
