Example 12: Simple assumption model for irregular raft

altDescription of the problem

To verify the simple assumption model of ELPLA, the contact pressure distribution of an irregular foundation obtained by Bowles (1977) (Example 9-6, page 265) is compared with that obtained by ELPLA.

A square foundation has 10 [m] side is chosen. The foundation is subjected to a column load of 540 [kN] at the center. It is required to determine the distribution of the contact pressure when the corner is notched as shown in Figure 16.

The notch has the following properties:

 

Area A = 4.5 [m2]
Center of gravity from o in x-direction x! = 3.5 [m]
Center of gravity from o in y-direction y! = 4.25 [m]
