Afloor in an office building is made of a reinforced concrete slab 10 in. deep and spans 20 ft. for the purposes of calculating the tributary load you can assume the slab is 10 ft. wide. this scenario can be modelled as a simply supported beam, 20 ft. long, 10 in. deep and 10 ft. wide.

calculate the maximum factored maximum moments and shears on this structure using the appropriate load combinations discussed in class.
note which loading combination is critical.

you can assume the uniform live load is 50 psf.

hint: since this is not a member that carries lateral load, there are no significant wind or earthquake loads contributing to the shear and moments in the member.
since this is not on the roof there are no roof or snow loads. h = 10 in. 20 ft.
