Introduction

This video covers Hold-Down Design and Drag Struts in shearwall analysis. It explains how the Hold-Down Design Table summarizes tensile forces, capacity, and force-to-capacity ratios, with a Design Summary page for quick pass/fail checks. Drag struts transfer loads from diaphragms above non-shear walls to adjacent shear walls, but their design is not included in the Program. In Canada, seismic design factors increase drag strut forces by 20% as per CSA 086.

Résultats de l'apprentissage

A la fin de cette leçon, vous serez capable de :

• Interpret hold-down design results in Shearwalls Program to assess tensile forces, resistance capacity, and critical response ratios for structural compliance.
• Analyze drag strut force distribution to understand load transfer from diaphragms above non-shearwalls to adjacent shearwalls in lateral force-resisting systems.
• Evaluate hold-down pass/fail criteria using design summary results to determine whether shearwall connections meet load resistance requirements.
• Apply CSA O86 seismic design standards to adjust drag strut force calculations and assess compliance with Canadian structural regulations.
