A square footing of size 2.5 m x 2.2 m is founded at a depth of 1.2 m below the ground surface in a homogeneous cohesionless soil having an angle of shearing resistance (o) = 380. The water table is at the foundation level. The saturated unit weight of soil (Ysat) is 18 kN/m³ and bulk unit weight of soil above the water table is 15 kN/m³. Determine: a. The ultimate bearing capacity of the soil (using MEYERHOF'S method). b. The net allowable bearing pressure for Fs = 3. c. The allowable load the footing can carry. d. If water table reached to the ground level, what will be the change in ultimate bearing capacity of the soil (using MEYERHOF'S method)?

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.
