How to Design Wood Columns | Design Example : IBC & NDS

📌 Understanding Column Design with the NDS & IBC 📌 In this video, we dive into column design using the National Design Specification (NDS) and the International Building Code (IBC). We'll explore key concepts such as: ✅ Buckling vs. Crushing – Understanding stability and material failure in wood columns ✅ The Euler Buckling Equation – When does a column fail due to instability? ✅ The Ylinen Formula & NDS Approach – Understanding how buckling and crushing interact. ✅ Step-by-Step Design Example – 4×6 Douglas Fir-Larch #1 column (10 ft height) By the end of this video, you’ll have a clear understanding of how the NDS and IBC codes regulate column design, ensuring both safety and efficiency in wood construction. 📌 Timestamps: 00:00 Introduction to Buckling and Crushing of Columns 03:23 IBC and NDS Code - Allowable Stress Design 05:24 Column Design Example (Layout and Loading) 08:54 Column Lumber Grade & Species 10:47 Design : Slenderness (and buckling) 18:20 The Ylinen Equation 19:31 Reference Design Values 20:48 Adjustment Factors. 26:20 The Column Stability Factor 31:27 The Adjusted Design Value - Compression Parallel to Grain 34:10 The Final Question 🔗 Resources: 📖 2024 NDS: Access the latest National Design Specification for Wood Construction here: https://awc.org/publications/2024-nds/ 📖 2024 NDS Supplement: Find the design values for wood species in the NDS Supplement: https://awc.org/publications/2024-nds... 📖 Residential Structural Design Guide: A great resource for residential design, published by HUD: https://www.huduser.gov/portal/public... 📖 John J.
