Example 5.2: Design Example of a Square Foundation for a Colum
Figure A.3a shows a square column foundation with the followin
conditions:
Live load=L=675 kN
Dead load D= 1125 kN
Allowable gross soil-bearing capacity 145 kN/m²
Column size-0.5 m x 0.5 m
-20.68 MN/m²
1,413.7 MN/m²
Let it be required to design the column foundation.

Example 5.3: Design Example of a Rectangular Foundation for
Column
This section describes the design of a rectangular foundation to support a column having
dimensions of 0.4 m x 0.4 m in cross section. Other details are as follows:
Dead load D= 290 kN
Live load L= 110 kN
Depth from the ground surface to the top of the foundation = 1.2 m
Allowable gross soil-bearing capacity = 120 kN/m²
Maximum width of foundation = B = 1.5 m
f, = 413.7 MN/m²
f=20.68 MN/m²
Unit weight of soil = y = 17.27 kN/m³
Unit weight of concrete = y₁ = 22.97 kN/m³
General Considerations
For this design, let us assume a foundation thickness of 0.45 m (Figure A.4a). The weight
of foundation/m² = 0.45 y = (0.45) (22.97) = 10.34 kN/m², and the weight of soil above
the foundation/m² = (1.2)y = (1.2) (17.27) = 20.72 kN/m² Hence, the net allowable soil-
bearing capacity Iqata] =120-10.34-20.72 = 88.94 kN/m²
The required area of the foundation = (D+L)/4(all) = (290 + 110)/88.94 =
4.5 m². Hence, the length of the foundation…
Problem 1
You are in the process of designing a water supply system for the whole lligan City, and
the design life of your system is to end in the year 2070. The population in the town has
been measured every 10 years since 1980 by the Philippine Statistics Authority, and the
reported populations are tabulated below. Estimate the population in the town using (a)
arithmetic growth projection, (b) geometric growth projection (exponential formula), (c)
declining growth projection (assuming a saturation concentration of 480,000 people), and
(d) logistic curve projection.
