The roof deck slab of Fig. P15.7 is intended to carry a total factored load, including self-weight, of 165 psf. It will have fixed supports along the two long sides and one short side, but the fourth edge must be free of any support. Two 16 in. square columns will be located as shown.

(a) Determine an acceptable slab thickness.

(b) Select appropriate load dispersion lines.

(c) Determine moments at all critical sections.

(d) Specify bar sizes, spacings, and cutoff points.

(e) Check controlling sections in the slab for shear strength
