A strip footing for a masonry wall is 1.1 m wide and is supported by the soil profile shown in the figure. What design loading can be imposed on the strip footing per meter of length? Use a factor of safety of 3. Ignore the depth factor terms in the bearing capacity calculations. However, you do want to compute the net bearing capacity, so you need to account for the weight of material removed in constructing the footing. To do this assume that the removed weight is equal to the depth of the footing multiplied by the unit weight of the upper soil.

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.
