A circular footing is 2.37 meters in diameter. The bottom the footing is 2.69 m. below the ground surface. Moist uni weight of soil is 17.26 kN/m3, Saturated unit weight is 19.22 kN/m3. Cohesion of soil is 90 kPa. Use Nc = 25.04, N = 12.05, Ny = 8.92. If the ground water table is located at a depth of 1.01 meters from the ground surface, determine the allowable load (in kN) that the footing can carry. FS = Round off to two decimal places.

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.
