Building Structural Design - Inelastic Effective Length Factors

Chapter 5: Structural Steel Columns - ASD Design, Part 6

         

Description:

          This application computes the stiffness reduction factors for inelastic behavior (Table A, page 3-8 of the AISC Manual), the stiffness ratios at the ends of the column (G values), and the effective length factor k for sidesway permitted. Mathcad's root function and solve block are used to compute the stiffness reduction factors and to solve the transcendental equation for effective length factors, eliminating the need to use the alignment chart in the AISC Commentary.
