A footing supporting a 2 ft x 2 ft column load carring 550 kips (dead load) and 200 kips (live load). The foundation level is 5 ft below the ground surface. The gross allowable bearing capacity is 6 ksf. The unit of soil is 130 pcf. You are required to provide complete design calculations for bearing, shear, and flexure for the strip footing. Assume f = 4 ksi, fy = 60 ksi.

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.
