I've got a project where a big I-beam is required. I routinely try to frame secondary framing into the web of the primary I-beams to reduce the unbraced length of the beam. But I've got an issue where the depths are not close. A W27x84 and smaller "joists" - W16x26. I don't want to increase the beam size any more than I have to....it is spanning 59 feet and I need to find a way to reduce the unbraced length. I don't think the architect will go for kickers from the bottom flange. I would appreciate thoughts on the idea attached.
