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.

Design a footing supporting a 400x400 concrete pier for a factored load of 600 kN using a factored bearing capacity of 300 kPa. The footing design need not be optimized, but should be practical for construction (ie. round-up dimensions). Ensure the design considers shear and bending effects on the footing. Concrete compressive strength (f′c) = 25 MPa, steel reinforcing yield (fy) = 400 MPa. Minimum concrete cover is 25 mm.
