A floor consists of 8 steel beams/girders supporting three 1-way slab panels. The
beams are supported on 6 columns around the perimeter of the roof. The roof is
subjected to a uniform pressure of 150 psf . All beams and girders weigh 90lb//ft.
Use free-body diagrams and statics equations to determine the load and reactions
on all the beams (Beam 1, 2, 3 and 4), girders (Girders 1 and 2), and columns
(Columns 1, 2 and 3).
(we only focused on one-way slabs in the class + pls include FBDs)
