SITUATION

Design a square column footing for a $400-mm$ square tied interior column that supports a dead load

of $890kN$ and a live load of $710kN.$ The column is reinforced with $8pcs25-mm-$diameter

longitudinal bars, the base of the footing is $1\mathrm{.}6m$ below grade, and the soil weighs $15\mathrm{.}7k\frac{N}{m^3}.$

The allowable soil pressure is $240$kPa. Use concrete strength of $21$MPa and reinforcement

strength of $420$MPa.

Provide the following:

Calculation for the footing design in shear check and flexure reinforcement.

Calculation for the design of development for footing reinforcement. Use

${}_t={}_e={}_s==1\mathrm{.}0$ and assume that the bars are spaced $300mm$ on centers leaving $150$

$mm$ on each side. Check $C_b$ and let $K_{tr}=0.$

Provide detailing sketch similar to the given example.
