Introduction

This video explains the “Components and Cladding” (C&C) section in shearwall design, focusing on wind loads affecting wall sheathing and fasteners. C&C wind design is separate from shear design and considers worst-case scenarios by combining external suction and internal pressures based on SPDWS.

The program calculates sheathing and fastener capacities, accounting for windward bending, leeward nail withdrawal, and potential failure due to moisture conditions. Designers can adjust inputs, such as building openings and fastener placement, to optimize performance in high-pressure zones.

Learning Outcomes

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

• Explain the distinction between Components and Cladding (C&C) wind design and wind shear design in shearwall analysis.
• Identify how worst-case wind loads are determined using external suction, internal pressure, and SPDWS.
• Analyze the impact of factors such as building openings, fastener placement, and moisture conditions on sheathing and fastener performance.
• Apply software-generated design ratios to assess and optimize shearwall components for wind resistance.
