A rectangular combined footing 8 ft * 20 ft is founded at a depth of 6 ft on a normally con-solidated sand deposit. The sand deposit is approximately 28 ft thick and overlies sandstone. CPT tests indicate the sand is relatively uniform below the proposed footing depth and theaverage tip resistance is 50 tsf. The total service load carried by the combined footing is480 k. Estimate the settlement of this footing.

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.
