Point Loads on Steel Bar Joists
Point Loads on Steel Bar Joists
(OP)
What is the maximum distance a point load should be placed from the actual panel point of a joist and how much can that load be before supplemental struts need to be added? For example, is a load of 80 lbs 12" from a panel point to much without adding a strut if the joist has adequate shear and moment capacity?

The amount of load that I allow is dependent upon the size of the joist and anticipated size of chord. Chords may vary from 1 x 1 and 2 x 2 for "K" series; 2 x 2 to 4 x 4 for "LH" series and 4 x 4 to 6 x 6 for "DLH" series.
Some older joists may have "hat sections" or "rods". I do not allow any concentrated loads to be hung from rods.
