A long footing supports a wall carrying a load of 260
kN per m. The soil at the
site is saturated clay having a undrained shear strength of 117
kPa. The unit
weight of the clay is 22 kN/m³ and it is suspected that
occasionally the water
table rises to the ground surface. What width in m (1 dp) of
footing should be
used if a minimum factor of safety of 2.4 is required? The footing
depth is 1.2 m

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 rectangular footing
(0.75m∙0.75m),
embedded 0.5 m, carries a downward column load of
200 kN. The footing is supported on an
overconsolidated clay with the following properties:
Cr = 0.05
e = 0.7
OCR = 2.0
PI = 55
cu = 200 kPa
ϒsat = 16.2 kN/m3
The ground water table is at a depth of 1.0 m below the ground
surface.

a circular footing 10m in diameter is proposed to carry a total
load of 9000 KN. The footing is to be placed at a depth of 2m below
ground surface. The soil is normally consolidated silty clay with a
unit weight of 20KN/m^3 and undrained shear strength of 50 KPa.
1) determine the short-term factor of safety using the General
bearing capacity equation.
2) Calculate the expected consolidation settlement of the
footing if the compression index is 0.2 and the...
