A solid slab $8$ m long $3m$ wide $175mm$ deep is supported by

concrete beams. The beams are $200$ mm x $500$ mm in cross$-$

section and rest on two end columns. The live load on the slab is

$2\mathrm{.}5k\frac{N}{m^2}.$ The characteristic strength of the concrete $(C\frac{40}{45}),$

$f_{ck}=40\frac{N}{m}{m}^2$ and steel, $f_{yk}=500\frac{N}{m}{m}^2.$ The unit weight of

concrete can be assumed as $25k\frac{N}{m^3}.$ Assume the durability

cover $=25mm,$ fire cover $=20mm.$

Q$1$ Determine the Ilusuerainforcement requirted for the stab.

Cheek for shear and defletion can be performed after Week

Assume $=0\mathrm{.}85.$

Q$2.$ Determine the flexural reinforcement for the beam. Checks

for shear and deflection can be performed after Week $2.$ For

shear links, use steel of $f_{yk}=500\frac{N}{m}{m}^2.$
