6. Steel Column Analysis Span B -- -- -- For the given axially loaded steel W-section, determine the maximum floor live load capacity, P LL. Assume the column is pinned top and bottom: K = 1.0, and there is no intermediate bracing. Use AISC-LRFD steel equations to determine phi Pn and the load. E = 29000 ksi. Span A -3- DATASET: 1 -2- W-section Fy Span...
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...
The billboard sign shown weighs 4000 lb and is supported on a 15" circular hollow steel tube with 3/8" thickness. The sign will be built in west Mobile and is subjected to wind forces with maximum wind speed of 160 mph. The hollow steel tube has a maximum compressive/tensile strength of 50 Ksi and a maximum shear strength of 10 Ksi. Determine if the hollow steel tube has enough axial and shear strength to support loads applied to the sign....
