Introduction

The video explains shearwall deflection, hold-down displacement, and storey drift analysis using an example model. It covers deflection calculations based on different force directions, material configurations, and the choice between non-linear four-term and linear three-term equations. The hold-down displacement table details uplift forces, elongation, slippage, wood shrinkage, and crushing, which contribute to total vertical displacement. Finally, the maximum storey drift is compared against National Building Code (NBC) limits to determine compliance, ensuring the design meets structural safety standards.

Résultats de l'apprentissage

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

• Analyze the factors affecting shearwall deflection, including force direction, material configuration, and equation selection (4-term vs. 3-term).
• Interpret hold-down displacement components such as uplift forces, elongation, slippage, wood shrinkage, and crushing to assess their impact on total vertical displacement.
• Calculate storey drift using deflection results and compare it against National Building Code (NBC) limits for structural compliance.
• Evaluate the suitability of different deflection and drift analysis methods (deflection-based vs. capacity-based) for shearwall design.
