Question $2$

a$)$ An engineer is given a task to design a slab with the dimension of $3\mathrm{.}5m$ wide and $4\mathrm{.}55m$ long. The slab is subjected to finishes and variable load of $1\mathrm{.}2k\frac{N}{m^2}$ and $3\mathrm{.}5k\frac{N}{m^2},$ respectively. If one short edge of slab is not cast monolithically with other slab panel and the other edges are casted monolithically to other panels, design the longitudinal reinforcement for this particular slab. Assume the slab thickness is $150mm.$ Use $f_{ck}=C\frac{25}{30}$ and $f_{yk}=500$MPa.

b$)$ A simply supported slab with the dimension of $3\mathrm{.}5m$ wide and $7\mathrm{.}2m$ long was subjected to finishes load and variable load of $1\mathrm{.}2k\frac{N}{m^2}$ and $3\mathrm{.}0k\frac{N}{m^2},$ respectively. Propose the slab thickness and design the reinforcement for this slab. You are also required to ensure that the slab must fulfill the basic span to effective ratio based on EC $2.$ Use $f_{ck}=C\frac{25}{30}$ and $f_{yk}=500$MPa.
