A proposed office building will include a 10 ft x10 ft square, 3 ft deep (the footing height is also 3 feet) spread footing. The normally consolidated clay has the following engineering properties: Ydry = 115.0 pcf $'=24° c'= 90.0 psf Cc/(1+eo) = 0.15 The soil stratum extends to a great depth, and the ground water table is 50 ft below the ground surface. What is the maximum bending moment from the earthquake that this foundation can support? Consider bending moment only about one axis.

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.
