Introduction

This video explains how to interpret shear results in Shearwalls Program, focusing on wind design using a flexible diaphragm. Shear results are categorized by shearlines (north-south and east-west), story levels, and wall segments, with key parameters such as shear force, sheathing resistance, hold-down effect factor (Jhd), and panel buckling resistance. The program calculates a shear force-to-resistance ratio, where values over 1.0 indicate wall failure, triggering a warning in both the shear results table and design summary. Proper coordination of wall groups and materials ensures accurate analysis and compliance with CSA O86 standards.

Résultats de l'apprentissage

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

• Interpret shearwall design results in the Shearwalls Program to assess shear force distribution, resistance factors, and structural capacity compliance.
• Differentiate between shearline categories (north-south vs. east-west) and segment groupings to accurately analyze shearwall performance at various story levels.
• Analyze the shear force-to-resistance ratio to determine whether a shearwall meets design requirements or fails due to capacity exceedance.
• Apply CSA O86 design standards to evaluate the impact of materials, hold-downs, and diaphragm assumptions on shearwall performance.
