This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to correctly calculate the slenderness ratio (KL/r) for steel columns. - The importance of selecting the correct effective length factor (K) based on column end conditions. - Why the weak-axis radius of gyration (r_y) is the critical value for buckling in unbraced wide-flange shapes. - How to apply the AISC threshold of 4.71√(E/F_y) to distinguish between elastic (slender) and inelastic (stocky) buckling. - How to avoid common FE exam traps, such as unit conversions and selecting the incorrect buckling stress formula.
