A square footing 1.6 m x 1.6 m is located at a depth of 1.2 m below the ground level in a sandy soil of unit weight 20 kN/m³. Angle of internal friction of the soil is 20° for which bearing capacity factor are N = 17.7, No = 7.4, N = 5. If the water table is very deep below the ground level then FOS = 3, the safe load carrying capacity (in kN, rounded off to nearest integer) of footing is

Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.
