Question

Problem 4 A W 14x120, A992 column has an effective length of 31 ft about both axes. Determine the LRFD design strength, φΡ,· Evaluate local buckling using the Specification equations and verify your result using footnotes from Table 1-1 and Table: 41 . Compute Fe and фР, using Specification equations and check using Table 4-14. .Use Table 4-1a to check the final results of your manual calculations. If this column is loaded to failure, would the behavior be inelastic buckling or elastic buckling?
