Problem II

For the given rectangular continuous beam, it is required to:

a$)$ Design the beam section using the ultimate limit state method.

b$)$ Calculate the deflection and compare it with code limits$.$

c$)$ Check the crack width of the beam.

Assume: Service Loads

Live Load $=1\mathrm{.}5\frac{t}{m}$

Dead Load $=1\mathrm{.}0\frac{t}{m}$

$f_c=300k\frac{g}{c}{m}^2$

Steel $f_y=360$MPa

Sustained Live Load $=60\%$ over $12$ months
