Question: Please show all steps and include all equations do not leave anything out 1 . Determine the maximum combined loads using the recommended AISC expressions

Please show all steps and include all equations do not leave anything out
1.Determine the maximum combined loads using the recommended AISC expressions for LRFD: =100 psf,L=70psf,R=12psf,Lr=20psf and S=30psf
2.Structural steel beams are to be placed at 7 ft 6 in ion center under a reinforced concrete floor slab. If they are to support a service dead load of D=64 psf of floor area and a service live load L=100 psf of floor area, determine the factored uniform load per foot which each beam must support using the LRFD expressions.
