FOUNDATION AND RETAINING WALL 1

Solve the given problems below. Use load combination of 1.2DL + 1.6LL
1. A column 450mm square with fc' = 27.65 MPa reinforced with 8-25mmø or Fy= 348 Mpa
supports a dead load of 1000 kN and a live load of 780 kN. The allowable bearing pressure is
240 KPa. The base of footing is 1.5m below the grade. Assume the weight of soil and concrete
to have an average unit weight of 19.7kn/m3. The total depth of footing is 550mm with an
effective depth of 475mm. Determine the following:
1) dimension of footing.
2) Value of two-way or punching shear force (Vu)
3) Value of one-way beam factored shear force (Vu)
4) Required moment for strength design (Mu)
5) No. of 25mmø bars in each direction.
