Steel roof joist modification
Steel roof joist modification
(OP)
I have a situation where a roof deck (100 psf LL) is being added above a 40' span of open web steel roof joist. To get additional load capacity our plan is to add a center support to the joist to increase load capacity. The center will be modified to provide for "end" bearing. All diagonals and angles are of consistent size throughout the length of the joist.
Anyone done this before? Any advice or cautions?
Thanks.

Otherwise, 100 PSF seems pretty high.
