The drawing illustrates structural steel beam-to-column moment connections presented in elevation, section, and plan views. Key components include wide-flange columns and beams, continuity plates with specified thicknesses, complete joint penetration welds, and erection bolts. The assembly transfers moment forces between the framing members and the column web.
