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 N_c, N_q et N_γ;
• Base inclination correction factors b_c, b_q et b_γ;
• Shape correction factor s_c, s_q et s_γ;
• Loads inclination correction factors i_c, i_q et i_γ.

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. Also, CiviLab provides high quality reports and archive them properly
