Typical Detail at Additional Concentrated Point Load

Elements

About this detail

When concentrated point loads greater than 100 pounds on open web joists or girders are located more than six inches from panel workpoints at either the top or bottom chord, additional diagonal web members consisting of L2x2x3/16 angles shall be furnished and installed by the contractor at the load location unless noted otherwise. Single or multiple concentrated point loads totaling 100 pounds or less can be placed at any point along the top or bottom chord between adjacent panel points without meeting these reinforcement requirements. A maximum limit of four concentrated 100-pound point loads per joist or girder is permitted on spans of 12 feet and greater, with one concentrated 100-pound maximum load allowed on spans less than 12 feet unless specified otherwise on the structural drawings. Joist bridging shall never be utilized to support hanging loads.
