Nourin · Foundation calculations

Bearing capacity from the dynamic penetrometer

From the penetrometer profile entered in CiviLab, Nourin calculates the allowable stress under the foundation, depth by depth.

What Nourin reads in the sheet

  • The dynamic resistance profile of the test and the penetrometer type;
  • The foundation geometry: width B, length L and embedment depth;
  • The safety factor and the correlation coefficient β, between 5 and 7;
  • The applied service load and the project unit system;

What Nourin does with it

  • Converts the dynamic resistance into failure stress using the Cassan and Sanglerat correlation;
  • Calculates the allowable stress over the requested depth range;
  • Checks the service load against the capacity obtained;
  • Produces the results table by depth step;
