This structural detail establishes sizing criteria for angle brace kickers supporting concentrated loads at steel joists and roof deck assemblies. The schedule correlates brace lengths ranging from up to four feet to over twelve feet with corresponding angle brace sizes and weld plate dimensions. For shorter spans up to four feet, single L2x2x1/4 angles are paired with 4"x4"x1/4" plates, scaling up to double L3x3x1/4 angles and 5"x5"x3/8" plates for lengths exceeding twelve feet. Full-height stiffener plates are required on each side of the steel beam at the kicker location, with steel beam and roof deck sizes configured per plan.
