If the soil exerts a trapezoidal distributed load on the bottom of the footing, determine the intensities w1 and w2 of this distribution needed to support the column loads 60kN, 80 kN and 50 kN. Please note there is a column moment of 10 kNm in counter clockwise direction also and this must be considered in the computation.

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.
