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.

Learning Outcomes

By the end of this lesson, you will be able to:

• 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.
