Concept explainers

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.

Question

A strip footing (6 m wide) is designed for a total settlement of 40 mm. The safe bearing
capacity (shear) was 180 kN/m2 and safe allowable soil pressure was 150 kN/m2. Due to
some reason, now the footing is to be redesigned for total settlement of 25 mm. The new
width of the footing will be
