Question Answered step-by-step A roof section is shown below and the roof plan is shown on the… A roof section is shown below and the roof plan is shown on the next page. The roof plan is part of a multiple bay structure with rectangular 32’x50′ grid in both directions. Assume 5 psf for Mechanical/Electrical/Piping (MEP) system. Assume a load between zero and 2 psf for Miscellaneous loads. a. Use Tributary area method to develop a dead and live load take-off table based on the roof construction shown.  b. Draw free body diagrams (FBD) for each of a typical open web steel joist, W21 x 50 beam and W14 x 53 column. Indicate the type(s) and magnitude of loading on the FBD. Recall that the weight of steel sections is given in lbs/ft by the second number in the member designation. The floor-to-floor story height is 14 ft. Weights:5 ply composition roofing w/ gravel = 6.5 psf 1 in. rigid insulation = 1.5 psf 22 gauge steel deck = 1.5 psf Open web steel joists – at 4 feet o.c. = 14 plf  Suspended acoustic tile ceiling –> suspended metal lath and gypsum plaster + acoustical fiber tile = 10 psf + 1 psf = 11 psf???having a lot of trouble with this problem, any help is much appreciated.
