A steel angle is bolted to a gusset plate with three 20 mm diameter bolts, as shown in the figure. The bolt spacing is 75 mm and the end spacing is 35 mm. The plate and angle are of ASTM A36 steel, with a specified minimum yield stress of 250 MPa and a specified minimum tensile stress of 400 MPa. The angle is 102x102x9.5 mm. The gross area is 1850 square mm. The dimensions x(bar) and y(bar) are both equal to 28.7 mm.

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.
