GGU-SETTLE: Final comparison of rectangular/triangular foundation analysis

A comparison of calculation results for rectangular and triangular foundations will show that there are minor differences in the calculated settlements. This is because of the different calculation point of the limiting depth. With rectangular foundations, the limiting depth is determined in the foundation centre. Triangular foundations do not "know" the centre point of the rectangles. For triangular foundations, the limiting depth is determined at the centre of the triangles, which deviates from the centre of the rectangles. If you select the "Limiting depth = profile base" check box (see Section “Specify limiting depth (Ex. 1)“), you will get the same results in both cases, as the limiting depth is then the same for both procedures.
