A rectangular footing 2 m x 3 m carries a column load of 600 kN a at depth of 1 m. The footing rests on a c-O soil strata 6 m thick, having Poisson's ratio of 0.25 and Young's modulus of elasticity as 20000 kN/m2. The immediate elastic settlement of the footing occurs as soon as the load is applied. The depth of the footing after immediate settlement from original ground level will be. (Take I = 1.06) mm. %3D

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.
