A $5-$Storey school building has the plan as shown below. The siab is cast monolithically with the beams and columns. The slab is cast monolinically with the beams and columns. The ficor stab has a superimposed tive load of BO psf and a superimposed dead load of $140$ pst$.$ The dead weights of the members are not. included. The concrete strength throughout the building is $4000$ pei and the steel reinforcement has a strength of $60000$ psi.

Q$2$

Design the L$-$beam along the exterior end span A for moment forces only. Assume a $=3$ stirrup is used for shear. Use the largest span to determine the minimum depth re$$ured$,$ and design for a bearn web width, b$==12$ in$.$ Sketch the final layout of the beam with the required reintorcement.

Q$3$

Design the column along gridine II A using the interaction charts. Determine the point load acting on the colurn from the distibuted load of neighbouring beams. Assume an adsional point load from the colum above of $200,000$ ib Use a $12x12$ column with reinforcement on $2$ taces and eccentricity of $4$ in$.$ Use th $=8$ in$.$ Sketch the final layout with the required ieinlorcement.

$91$

Design the foot flab using the end span between gridlines I and II$.$ Use a slab height of $5$ in and include ACr check for deflections. in addition to longitudinal steet, inctude the design for temperature and shrinkape reintorcement. Use a mavimum positive moment $=$ wial $14$ and a maximum negative moment $=\frac{w}{2}\frac{?}{12}.$ Shatch the finat lajout with reirforcement.
