Concentrated Loads On LH Joists
Concentrated Loads On LH Joists
(OP)
Looking at a vintage Vulcraft joist catalog, they noted that concentrated loads are allowed on LH joists (without specifying special design) provided that the moment and reaction do not exceed 85% of the allowable values and that the concentrated load doesn't exceed 12% of the allowable reaction.
Are those unique to Vulcraft joists or were they standard practice, and perhaps an SJI spec guideline?

The question is whether that was a general SJI design approach applicable to other manufacturers.
