Problem $1.$

Design a one$-$way slab to carry a live load of $90$ psf and an external dead load of $50psf.$ The

slab simply supported over a span of $15ft.$

Note: Don't forgot to include the self$-$weight of the slab in your ultimate moment

computation.

a$)$ Select the main reinforcement and spacing

b$)$ Design the temperature and shrinkage temperature and spacing

$f_c^{\text{'}}=4$ksi and $f_y=60$ksi

Problem $2.$

Compute the design strength of the concentrically loaded short columns below. For each

section design the stirrup $($rebar size and spacing$)$

Assume $f_c^{\text{'}}=4$ksi and $f_y=60$ksi.
