Select the most economic A992 (Fy=50 ksi) W shape to use as a column for the following conditions. Axial dead load of 75 kips, axial live load of 75 kips, length of the column is 12 ft, with no intermediate bracing, pinned top and bottom 2, 3. Use table 10.6 to answer the following questions about A36 double angle compression struts, pinned at both ends. A double-angle compression member 8 ft long is composed of two A36 4x3x5/16 steel angles....
Problem 2. Design and select an ASTM A992 (Fy" 50 ksi) W-shape column to carry an axial dead load of 140 kips and live lond of 420 kips. The column is 30 feet long, and is pinned top and bottom in both axes. In addition, the column is laterally braced about the y-y axis (local weak/minor axis of the section) and torsionally braced at the midpoint. Limit the column size to a nominal 14 in. shape, that is W14 shape...
Problem 5: Select the lightest steel beam. Fy=50 ksi. The lateral bracing is provided at the both ends and at the two points 10 ft each from the ends. Neglect Mn Fy 2 weight of the beam.

Given w 14 x 145, A992 Grade 50 (Fy = 50 ksi) steel shape is used for column AC in Fig.1. Service load P = 1,000 kips (70% dead load and 30% live load). Required: Is the column safe, based on LRFD?
2. Buckling. (10pts) The A-36-steel W12 x 50 column is fixed at its base. Its top is constrained so that it cannot move along the x-x axis but is free to move along the y-y axis. Determine the allowable centric load the column can support if the safety factor is 2. Data: A= 1 Sin, 1, = 56in", 1.-394 in*, E-29x10,ksi.
Determine the allowable axial compressive load for a 25-foot long A992 W8X40 structural steel column using the AISC procedure as indicated in your textbook. The bottom of the column is fixed, an the top is pinned. Use the material properties and dimensions as indicated in the appendices of your textbook.
Using allowable stress design determine the allowable centric load for a column of 10-m effective length that is made from the following rolled-steel shape: W250x101 Use - 250 MP and E-200 PA-12,900x10*m? ry65.8x10 m
