Would you agree with this rule of thumb for beam supports?
(Assume fairly long spans for this discussion and double thick LVL’s)
I think all LVL beams in the ceiling that support 2nd floor loads with roof point loads on them too, should have a minimum of three 2x4's supporting each end with a minimum of 3 inch bearing surface.
I frequently see only two 2x4's on some beam ends.
Sometimes these beams even have another beam connected at mid span.
I would think that two 2x4's would maybe only be good if the beam was only for ceiling joists with no attic storage above and not very long span.
I think that even four or more 2x4's is necessary in many cases.
