A new type of beam-to-column connection for steel moment frames, designated as a “self-centering connection,” is studied. In this connection, bolted top-and-seat angles, and post-tensioned (PT) high-strength steel strands running along the beam are used. The PT strands tie the beam flanges on the column flange to resist moment and provide self-centering force. After an earthquake, the connections...
Traditional steel moment frames use welded beam-column connections, which are susceptible to brittle fracture and commonly have large residual deformation after the earthquakes. A novel beam-to-column connection for steel moment frame is proposed. Four full-scale new connections and two connections without self-centering capacity were tested under cyclic lateral load, the connections' strength property,...
