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.

Plate load test is adopted globally to determine in-situ bearing capacity of the subsoil and considered as one of the most important field test for any big construction project. A plate load test was conducted on a 300 mm side square plate at a depth of 1.10 m below the ground level in pure clayey soil for an important construction site. Failure of the soil occurred at a load of 45 kN. i. Calculate the safe bearing capacity of a 1.5 m wide square footing founded at a depth of 1.5 m in the same sub-soil. Assume the total unit weight and factor of safety of 18.2 kN/m and 2.0 respectively. ii. State any three limitations of the above mentioned test carried in field.
Scenario The wall footing at right is to be constructed to carry an inclined load at 85 degrees with the horizontal, as shown. Assume that there is impenetrable bedrock below the Sample point shown in the figure. 1) Calculate the expected primary settlement of the soil at the Sample point. Also, determine the time it will take for 60% of the expected primary settlement to occur. 2) Determine the factor of safety against bearing failure of the soil for the wall footing if qult of the soil is 160 kN/m2.
