Beam load is $12"*24"$

Data:

Use: Parking:

Dead load additional to own weight: $80$ psf

Live load: $100$ psf$,$

F$\text{'}$c: $4$ ksi,

Fy: $60$ ksi

Assume a parapet of $8$ blocks, whose weight will be $120$ pcf$,$

Allowable soil stress adm $=2,500$ psf$,$

First

Design the beams by determining the flexural steel of the simply supported beam. Also design the steel due to shear stress. Detail it considering the minimum and maximum ranges of steel, as well as its bar separations.

Second

Design the edge slabs to determine the steel to resist bending stresses. Consider them all in one direction. Detail it considering the minimum and maximum ranges of steel, as well as its bar separations.

Third

Design the columns for simple compression $($steel due to axial loads$).$ Detail it considering the minimum and maximum ranges of steel, as well as its bar separations. Use the minimum amount to select the area of $$steel to place. Make the iteration diagram, but only design it for the first case under only axial load. Considering an amount of $1\%.$ The columns will have a square section.
