Problem 4 A 22 ft long column in an existing building is part of a braced frame, both in the x-x and the y-y planes of the cross section. It is fixed at the base and pinned at the top for both axes. In addition, the column is laterally supported perpendicular to its weak axis at a height equal 12 ft from the base as shown. The column is W10x77 section A992 steel Grade 50 (i.e. Fy = 50 ksi). Determine (KxLx) and determine the maximum factored load that the column can support. Check local buckling. See figure.

An interior column is to be designed as a part of an unbraced frame system, located at ground floor. It is to be pin-supported at the foundation end, and it is to be connected by two W14x68 girders and W18x106 column at the other end. All of the members, including the column described, are made of A36. Architectural specifications require that the column is to be designed as a rolled W-section with depth of 21 inches. The column is expected to carry axial compressive load of 300 kN dead load and 350 kN live load. Length of girders is 4 meters and length of columns is 3.0 meters. Select the best section that should be used for the said column. For determining effective length factors, neglect inelastic action; and use major axis moment of inertia for girders and minor axis moment of inertia for columns. Use LRFD specifications from 2015 NSCP Vol. 1.
A plate girder cross section consists of two flanges, 11⁄2 inchesx 15 inches, and a 5⁄16-inch 3 66-inch web. A572 Grade 50 steel is used. The span length is 55 feet, the service live load is 2.0 kips/ft, and the dead load is 0.225 kips/ft, including the weight of the girder. Bearing stiffeners are placed at the ends, and intermediate stiffeners are placed at 69-20 and 12,-9,, from each end. Does this girder have enough shear strength? a. Use LRFD. b. Use ASD
