Supplementary web members utilizing L2 1/2x2 1/2x3/16 angles are installed on each side of the joist to span from the applied load location to the nearest opposite chord panel point. For field-installed wood nailers, attachment options include four three-quarter inch diameter thrubolts through shop-installed pipe sleeves with oversize washers, or steel side plates measuring one-quarter inch by four inches by nine inches secured with two three-quarter inch diameter thrubolts per joist space. Fillet welds of three-sixteenth inch size are specified at indicated member connections.
