How to Design Wood Floor Joists per the IBC & NDS (American Standards)

In this video, we dive deep into the structural design of wood floor joists according to the International Building Code (IBC) and the National Design Specification for Wood Construction (NDS). Whether you're an engineer, architect, or builder, this comprehensive guide walks you through every critical step of floor joist design. ✅ What You'll Learn: Bending Design – How to calculate and check bending stress in wood joists. Shear and Bearing Design – Ensure your floor joists meet shear and bearing capacity requirements. Deflection Checks – Learn to verify floor stiffness to prevent excessive sag or bounce. 2024 IBC & NDS Compliance – Follow code-specific guidelines for safe and reliable floor framing. By the end of this video, you'll have a clear understanding of how to design floor joists that meet structural safety and building code standards. ✅ Links: 2024 IBC Code: https://codes.iccsafe.org/content/IBC... 2024 NDS: https://awc.org/publications/2024-nds/ 2024 NDS Supplement: https://awc.org/publications/2024-nds...
