This structural steel fabrication detail specifies the geometric requirements for beam flange copes and weld access holes. The cutout incorporates a three-eighths-inch minimum radius and specified dimensions relative to the flange thickness denoted as tbf. A bevel is provided as required by AWS D1.1 for the selected groove weld procedure. Specifications govern the fabrication details including cutting methods and smoothness requirements.
