A W10 × 68 section consisting of 50 ksi steel is used for a 16 ft long beam-column in a braced frame. The member must support service loads Pp PL 60 k and 80 k and to service moments MDx = 40 ft-k, MLx = 45 ft-k, Mpy = 10 ft-k, and MLy = 15 ft-k. The moments are applied at both ends of the column so as to put it in single curvature about both axes. The column has K, = K, = 1.0 and C, 1.0. Is the member satisfactory? (Ans. OK 0.987 LRFD; NG 1.052 ASD)

A floor system supporting a 6 in. concrete slab is shown in Figure P11.4. The live load is 100 psf. Using LRFD, considering bending only select the most economical sections for: 1. The typical beam of A992 steel. 2. The typical girder of A992 steel. The concrete floor provides full lateral support for the compression flange for both the beams and the girders. Assume the weight of concrete for slab = 150 lb/ft^3
Using LRFD determine the maximum service load Q (kips) (Q is a live load) at the mid-height of the beam-column shown that is part of a braced frame (BF) system. Assume the member is hinged with respect to bending in both x and y directions at top and bottom. Additionally, lateral support occurs in the weak direction at mid-height. Axial compression service dead load is 100 kips and the live load is 150 kips. The section is W12x136 and A36 steel. Please determine Cb and use it to help your beam-column capacity. Take Cm = 1.0.
Determine the lightest, commonly used wide flange W250 section for the column shown below to support the factored axial load of Pf, = 2500 kN. Select a W250 section that is commonly used and is generally readily available. The column is 6m long. Consider pin support conditions at both ends of the column. As shown below, there are two lateral bracing members in the X direction, while no bracing exists in the Y direction. The steel is ASTM A992 steel and E = 200,000 MPa. Take note: (a) Your solution should include the iteration for selecting the lightest section. (b) Using tables in the CISC handbook.
The beam shown below has continuous lateral support of both flanges. The uniform load isa service load consisting of 50% dead load and 50% live load. The dead load includes the weight ofthe beam. If A992 steel is used, is a W16x31 adequate? Apply the Cb (moment gradient) factor tosolve for the moment capacity. Solve using LRFD only. As part of the solution draw the shear andmoment diagrams to scale and identify the max and min moments.
