$14\mathrm{.}7.$ The square slab shown in Fig. P$14\mathrm{.}7$ is supported by$,$ and is monolithic with, a reinforced concrete wall along the edge $CD$ that provides full fixity, and also is supported by a masonry wall along $AB$ that provides a simply supported line. It is to carry a factored load $q_u=14k\frac{N}{m^2}$ including its self$-$weight. Assuming a uniform $150mm$ slab thickness, find the required reinforcement. Include a sketch summarizing details of your design, indicating placement and length of all reinforcing bars. Also check the shear capacity of the structure, making whatever assumptions appear reasonable and necessary. Use $f_c^{\text{'}}=28$MPa and $f_y=420$MPa.
