The site for a commercial building project has the surface elevation lowered 2 m to improve area grading for building access, parking, and drainage. Foundations for interior building columns will be constructed at the level of the 340 new ground surface. Each foundation is 1.5 m by 1.5 m square and imposes a bearing pressure of 200 kPa. What net stress increase results in the soil 1.25 m below the center of the foundation? Assume Boussinesq conditions apply and soil unit weight is 18 kN/m3.

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.
