the span is 20 ft and support roof truss's on 24" centers and load requirements are 20 lb live load. this beam is open in the garage and sets on exterior walls. The garage door is located approx 2 ft out from this beam. The depth of the beam max would be 10" but I have a 4 1/2 x...
what size steel I beam would I need to replace a flitch beam that is constructed of 2 doug fir 2x12x20ft with steel plate bolted inbetween. this beam supports roof truss's on 24" centers and are approx 30' long with support in center.
