16.1 A continuous footing is shown in Figure 16.18. Using Terzaghi's bearing-capacity factors, determine the gross allowable load per unit area (qall) that the footing can carry. Assume general shear failure. Given: y = 17.5 kN/m³, c' = 21 kN/m², ' = 32°, D = 1 m, B = 1.5 m, and factor of safety = 3. Figure 16.18 B qall Unit weight of soil = y c' $' ⒸCengage Learning 2014

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.
