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 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) Calculate the primary consolidation settlement for this
footing.
b) Is the calculated Sc within...

What is the maximum tension (kN) on a cable carrying 2.5 kN/m
uniform load if the lowest point of the cable is 40m and 3m away
from the one of the support along the horizontal and vertical
direction respectively? Round off to 3 decimal places.

Design a square footing for a 18-inch. square column and a
superimposed dead load of 200 kips and a live load of 300 kips. The
maximum permissible soil pressure is 4000 psf. Use concrete with a
design strength of 3 ksi and grade 40 reinforcing bars with yield
strength of 40 ksi.
