structSU10, I have wrestled with the same "timing" issue for a while now and came up with the same solution that you suggested for the temporary support while the steel beam is lifted into place. There is a wall above, so I want to ere on the side over overbuilding temp supports.
The plan is to...
Dik, the joists are 2x6 but span only 7 feet. A bit undersized for my liking, but within acceptable span range and there appears to be very little flex/bounce. These rest on a notch in the glulam, back slightly less than 2”. No hangers, just nailed (ommon practice for 1969). There appears to...
Craig H - good points. I will consider the bearing plates idea.
On the issue of LTB, the steel beam would be about 8" x .285" x 6.5". I think that the number and spacing of the attachment points to the glulam would help control to some extent. A 6"x.32"x6" would also be sufficient and...
Thanks, MegaStructures. My thoughts also. There will be proper footers for the posts, so I don't see why this wouldn't work. I've just never done that before myself. Now, it might be a trick to get it trimmed out so that the beam(s) are covered well and look good, but should be doable.
Dealing with a 20' span in basement. Existing 6x10 glulam circa about 1970 spans 20' with one support post in the middle. Need to remove the middle support post and span the entire distance. A W8x28 steel i beam would do the trick,but, due to existing joists, plumbing, electrical, ductwork...
