A wall footing is to support a 400 mm wide reinforced
concrete wall with a dead load of 270 KN/m and a live load of 210
KN/m. The bottom of the footing is 1.50 m below the final grade.
Assume the soil weighs 15.78 KN/m3 and the allowable soil pressure
is 190 Kpa. Use 75 mm as concrete cover, fc’ is 28 Mpa, fy is 415
Mpa, and concrete weights 23.5 KN/m3. Compute the:
Width and depth of footing

A 400 mm concrete wall supports a dead load of 280 KN/m and a
live load of 230 KN. The allowable bearing pressure is 230 KN/m2
and the level of the bottom of the footing is 1.5 m below the
ground surface. Assume concrete weighs 24 KN/m3, that of soil is
15.74 KN/m3, fc’ = 20.7 Mpa, fy = 248 MPa,. Use 25 mm diameter
reinforcing bars. Thickness of footing = 500 mm and concrete cover
is 75 mm. Calculate...

A reinforced concrete bearing wall supports 12” wide beams
bearing on the full width of the wall spaced 10’ o.c. The bottom of
the wall is a fixed connection. The top of the wall is a pinned
connection. The wall is 20’ tall. The load from each beam, Pu, is
30 kips. Determine whether a 10” wide wall will work for this
condition. Select vertical and horizontal reinforcing steel.
