Assuming that the triple 2x12s beam is made of #2 southern yellow . For that, we use the deflection criteria provided by the 2012 International Building Code, stating that beams under a combination of dead load (permanent load) and live load (loads that can vary in time) should at most have an allowable deflection equal to the span of the beam divided by . Since the load is applied to this composite beam through the wood side pieces, the bolts must distribute that portion of the load that the steel plates will be carrying.
