Bearing capacity: laboratory tests

Footings are the bases laid on the soil on top of which a structure is erected. Thus, it is the foundation on which a building or any such structure stands upon. They are made of concrete having reinforcements inside them and are poured into an excavated ditch or conduit. Before the foundation is built, a test is done to assess the strength of the soil bearing capacity to ascertain the type of foundation to be built.

Ultimate bearing capacity is the maximum pressure a foundation can exert on the soil before a large scale failure occurs. Such failures can be catastrophic with collapse of the structure

CiviLab calculates the bearing capacity of an isolated footings from results of laboratory tests according to

  • NF P 94 261 (Eurocode 7);
  • DTR BC 2.331;
  • DTU 13.12.

According to standard NF P 94 261, CiviLab took into consideration both cases, namely:

  • Undrained conditions;
  • Drained conditions.

Based on the properties of the soil, the footing shape and the standard chosen, CiviLab determines the following factors:

  • Bearing capacity factors Nc, Nq et Nγ;
  • Base inclination correction factors bc, bq et bγ;
  • Shape correction factor sc, sq et sγ;
  • Loads inclination correction factors ic, iq et iγ.

CiviLab allows you to:

  • Calculate the bearing capacity of a shallow footing according to several standards;
  • Provide high quality reports;
  • Archive reports correctly.

With "CiviLab", you can easily calculate the bearing capacity of a shallow footing. CiviLab also provides high quality reports and archive them properly
