Determine the negative and positive moments required for the column strip of the Marked panel of the two-way slab with beam structure in the short direction shown in the Figure below. The slab is to support a live load of 120 psf and a dead load of 100 psf, including the slab weight. The columns are 15 in. x 15 in. and 12 ft long. The slab is supported by beams along the column line with the cross section shown. Determine the slab thickness and check the shear stress if fc = 3000 psi and fy = 60,000 psi.
