A test program was conducted on seismic-resistant steel moment connections constructed using Reduced Beam Sections with beam web openings. In the connection, in order to enhance ductility capacity under severe cyclic loads, a portion of the beam web near the beam-to-column connection is cut out instead of the beam flange as in dogbone connections. A total of 4 large scale specimens were tested in this program. The specimens were all made using $H-458{\times}417{\times}30{\times}50$ sections for the columns and $H-792{\times}300{\times}14{\times}22$ sections for the beams. Test specimens showed excellent performance similar to that of dogbone connections.
