Abstract:
This final project presents the bearing capacity, settlement and rotation that occurs in the
shallow foundations that are analyzed. This shallow foundation will support a tank load of 780,6
kN with a diameter of 3 m and a height of 6 m. The use of this shallow foundation is another
alternative in foundation construction because in carrying out a project it will be better if the
costs incurred can be minimized with a foundation design that remains optimal. Foundations are
one of the most important elements in a building. Its function is to distribute structural loads and
building floor loads to the ground below. Choosing the right type of foundation is very crucial
because it can affect the stability, strength and overall performance of the building. Calculations
of bearing capacity, settlement and rotation were analyzed on a foundation with a width of 4 m
and a length of 6 meters with a depth of 0,5 m.
Based on SPT data using the Meyerhof method, The bearing capacity of a shallow
foundation is 255,5 kN/m2. This is said to be safe because the soil tension is 66,4 kN. Based on
the results of calculations using Coduto foundation design principles, it was found that the
decrease that occurred in shallow foundations was 0,02 mm. This is said to be safe because the
allowable settlement in the tank structure is 25 mm. then regarding the rotation that occurs in
shallow foundations with predetermined dimensions. The analysis used uses the Bowles method,
then the rotation that occurs in the rectangular foundation analyzed is quite low with a value of
0,06 radians.
