A $5-$storey school building has the plan as shown below. The slab is cast monolithically with the beams and columns. The slab is cast monolihically with the beams and columns. The floor stab has a superimposed live load of $80$ 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 teinforcement 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 required, and design for a bearn web width, b$==12$ in$.$ Sketch the final layout of the beam with the required reinforcement.

Q$3$

Design the column along gridine $11$ A using the interaction charts. Determine the point load acting on the colurn from the distibuted load of neighbouring beams. Assume an addional point ioad from the colum above of $200,000lb.$ Use a $12x12$ column with reinforcement on $2$ toces and eccentricity of $4$ in$.$ Use ${}_{th}=8$ in$.$ Sketch the final layout with the required reinlorcement.

Q$1$

Design the floot tlab using the end span between gridines I and II$.$ Use a slab height of $5$ in and include ACI check for deflections. in addition to longitudinal steet, inctude the design for temperature and shrinkape reinforcement. Use a mavimum positive moment $=$ wala $14$ and a maximum negative moment $=$ w$/$al $12.$ Sketch the finat lajout with reinforcement.
