Скачать или смотреть Beam vs. Plate Buckling Explained: Effective Width, Reserve Capacity, and Design Standards

📝In this session, Wouter van den Bos, CEO of SDC Verifier, explains the fundamentals of plate buckling — how it differs from beam buckling and how engineers account for it in real-world design and standards.

You’ll learn how to:
✔️Recognize the difference between beam buckling and plate buckling
✔️Understand how edge support changes plate stability compared to free edges
✔️Learn why plates can still carry load after local buckling, unlike beams
✔️ Learn the concept of effective width and how it modifies capacity calculations
✔️Discover how imperfections, concentrated loads (e.g. crane wheels), and standards influence buckling checks
✔️ Compare how yielding and buckling interact when defining safe design limits

By the end, you’ll clearly understand how plates behave under compression, how effective width increases reserve capacity, and how modern codes translate these effects into safe and economical design rules.
