Self-weight of footing

"P = 23 kN\/m*8m = 184 kN\\\\\nP_T= 1.2 *184 kN = 220.8 kN\\\\\n"

From the M30 and the Fe415 design the beam

"W_T=\\frac{P_T}{A}\\\\\n120=\\frac{220.8}{A} \\implies A = 1.84 \\\\\n"

"Area = S^2 \\implies (B)= \\sqrt{1.84}= 1.35646"

The size chosen can be "1.5 m \\times 1.5 m"

Therefore area "= 2.25m^2"

Pressure

"P= FA \\\\\nP =496.8 N\/m^2"
