A two$-$way slab has been shown in the figure. Story height is $3\mathrm{.}50m$ and beams and columns dimensions are $4050cm$ and $5050cm$ respectively. Service live load is $5k\frac{N}{m^2}$ and the dead load is assumed only due to the weight of the slab. For the marked panel:

Determining the thickness for the panel,

Compute the bending moments in different areas of the panel and determine the longitudinal reinforcement of the slab and weight of concrete: $24k\frac{N}{m^3})$
