QUESTION $1($COMPULSORY$)$

A foundation base is required to support a $500$ square column subjected to a permanent load $(D_n)$ of $700$ kN and a Live load $(L_n)$ of $390$ kN $.$ Additionally, the column supports a permanent moment of $80$ kNm and a live moment of $40$ kNm $.$ The foundation base dimensions are $3500mm2600mm500mm$ depth. Design the foundation base reinforcements for the short and long direction and check for punching shear. The bearing pressure of soil is $200$ kPa $.$

Given

$f_{cu}=25$MPa

$f_y=450$MPa

${}_{cu}=24k\frac{N}{m^3}$

$c=50mm$
