Sizing a ridge beam.

Builders will probably like the revision to Table R802.5.2 that will require approximately 20% fewer nails in the rafter-to-ceiling joist heel joint connection. The rafter-to-ridge, collar tie, and ridge strap requirements have been clarified. The trigger for a ridge beam and its required bearing are revised slightly.species of glulam beams under dry‑use conditions. Bending moment and shear capacities are based on a normal (10‑year) duration of load. Dimensions shown are net sizes, and capacities are based on loading perpendicular to the wide faces of the laminations; that is, bending about the x‑x axis of the beam, as shown in Figure 1.Microlam Beam Size Calculator. Microlam beam size depends on factors like span and load.
