$($CLO$1$ and CLO$2)$

The floor shown in Figure I carries an ultimate pressure ${}_0=10k\frac{N}{m^2}($including all $DL$ and $LL),$ Design the beam DEF $($continuous beam$)$ for fexure and shear. All beams have width of $300mm$ and all column have sections $300300mm.$ Note, you must compute the thicknesses of the slab and the beams $($their weights are already included in $W_u$ above$).$

Concrete compressive strength is $23$ MPa and yielding strength of steel bars is $420$MPa. ${}_c$ is $25k\frac{N}{m^3}.$ Use bar size $10$ for stirrups, bar size $25$ for flexure, and clear cover of $40mm.$
