1. A ridge beam 1 ft wide by 2 ft deep in a roof system carries beams which are 36 in. apart o.c. The roof carries a uniform dead load in the direction of gravity of 30 psf (along the inclined length) and a uniform roof snow load of 25 psf (along the horizontal projection). a) Show the dead plus the snow load on a typical beam. Show the load along the inclined length in the direction of gravity. b) For the beam in part (a) find the reactions (assume the ends are simple supports) and then draw shear and bending moment diagrams. c) Show the ridge beam and the dead plus snow load on it. The unit weight of the ridge beam y = 31 lb/ft³. Draw shear and bending moment diagrams assuming the ends are simple supports. 51ft 12ft 키 12ft A 1 1.8 12ft S = 25 psf Section A-A iftk ✓ 12ft 1.
