Submit the following online or on paper: The footing below is a 5ft square. The soil immediately below the footing has a unit weight of 116 lb/ft^3, cohesion of 864 psf, and internal friction of 23 degrees. The soil above the base of the footing has a unit weight of 120 lbs/ft^3. What is the allowable bearing capacity of the soil? Can the soil safely support the 50 kip load shown?

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.
