These connection details show bottom flange lateral bracing configurations for structural steel beams. The assembly utilizes angle sections such as L4x3x3/8 and L4x3-1/2x3/8 or three-eighths-inch bent plates welded to the beam web and flange with quarter-inch fillet welds. Case options provide varying vertical distances from the beam flange, with minimum clearances of four to six inches and specific offset criteria based on the beam flange width. All connections are tied back to structural members sized per plan.
