Find the lightest W section for a tension member made of A572 Grade 50 steel. The axial tension in the member due to dead load is 70 kips due to live load is 10 kips. The connections at the end of the member include 7/8 in diameter bolts, one per line.
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...
Please refer AISC 15th edition 2. Select the lightest W shape to carry a uniformly distributed dead load of 0.5 kips/ft and a live load of 1.0 kips/ft on a simply supported span of 42 ft. Adequate lateral support is provided. The live load deflection is limited to 360, Use A572 Grade 50 steel and LRFD. (credit weight 30)

Find the lightest W12 Section to support the service compression loads listed below. The column is 30 ft long with the end connections as shown. The column is braced at mid-height but only in the strong axis. Steel is ASTM A572 Grade 50. Use the ASD method only. oku W2! IMIDTH SUPPORT CONDITION LOADS I DEAD = 1 2look TT LIVE = 1564
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?

Problem 2: the most economical (lightest) W shape to support a uniformly distributed load of 4k/ft (This load includes the weight of the beam) on a simply supported span of 25 ft as shown. Assume the yield stress of the steel to be 50 ksi. The deflection limit (Allowable) is Select 360 w 4 kips/ft 25'-0" R 50 kips RB 50 kips
2. Verify that a built-up ASTM A572 Grade 50 (Fy - 345 MPa) column with PL 205 x 25 mm flanges and PL 380 * 6 mn web is sufficient to carry a dead load of 300 kN and live load of 900 KN in axial compression. The column, having an unbraced length of 8 meters, is braced at the midpoint about the weak axts, the ends are pinned in both axes. (Use ASD, 15 pts)
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....
