Abstract: “The behavior of beam-column connections plays an important role in the response of a steel moment resisting and moment stiffness framed structure, especially under statically loaded. In this study, the moment-rotation characteristics of semi-rigid bolted connections using with top and seat angles is discussed based on experimental investigation. The aim was to provide necessary data to improve of the Eurocode 3.The maximum bending moment, the plastic flexural resistance, Mj.Rd and the bending moment capacity, MƟ.Cd increased with the increasing thickness of the top and seat angles joints.”
