Problem $3$:

A four$-$span one$-$way slab is supported on $12-$in$-$wide beams with center$-$to$-$center spacing of $14,16,16,14$ ft$.$ The slab has a superimposed dead load of $20$ psf and a live load of $100$ psf$.$ f$\text{'}$c $=3500$ psi and fy $=60,000$ psi

Sketch a segment of this floor plan showing the beam strip.

Select initial slab thickness to meet the minimum required thicknesses in ACI $318-19,7\mathrm{.}3\mathrm{.}1\mathrm{.}1$

Using ACI coefficients, calculate critical shear and moment values $($positive and negative$)$ along the slab strip length.

Design the slab reinforcement based on the largest negative and largest positive moments. Check ACI

requirements of strength, tension$-$controlled, minimum steel, bar spacing.

Check shear capacity.

Include temperature and shrinkage steel.

Sketch a cross$-$section of the slab showing the slab strip along its length showing location of reinforcement.
