GGU-FOOTING: Consider depth coefficients (Example 2)

In the bearing capacity equations in DIN 4017, the effects of the shear strength of the soil above the footing base are neglected. According to "Theoretical principles: Analysis of bearing capacity failure", this influence can be considered by applying the depth coefficients d_c and d_d.

An example will demonstrate the influence of taking depth coefficients into consideration. First activate the following check box in the "Edit/System parameters" menu item:

Analyse the system once again. Pressing [F5] is the fastest way to do it. After a short wait the base tilt message appears again, and after confirmation with "Yes", the following information:

The utilisation factor was improved from 1.050 to 0.861 by considering the shear strength of the soil above the footing base and is thus below the maximum allowable value of 1.0. Naturally, the base tilt is still there.
