Purpose and Background

Lateral-force resisting systems allow building structures withstand the wind and seismic loading specified in the building codes. This webinar explains how these systems function in wood-framed structures and which design approaches could be used for various types of buildings. The attendees learn the basics of designing both horizontal elements of the systems (diaphragms) and vertical elements (primarily shear walls). The frequently misunderstood issue of providing the load path between the horizontal and vertical elements rounds up the discussion. The webinar is based on the design requirements contained in the 2015 editions of the International Building Code and American Wood Council's Special Design Provisions for Wind and Seismic and includes a number of design examples.

Primary Discussion Topics

• Design of diaphragms in wood-framed buildings
• Design of shear walls that use wood structural panels
• Design of collectors (drag struts)

Learning Outcomes

Upon completion of this course, you will be able to:

• Identify horizontal and vertical elements of a lateral-force resisting system
• Describe the load path for resisting lateral forces in a wood-framed building
• Explain the design procedures for wood diaphragms in accordance with the International Building Code and American Wood Council's Special Design Provisions for Wind and Seismic
• Know the difference between a segmented and a perforated shear wall

Webinar Benefits

• Become familiar with the differences between flexible and rigid diaphragms
• Learn to design wood-framed diaphragms for strength and deflections
• Find out how to design perforated wood-framed shear walls
• Examine the wood-based materials used in diaphragms and shear walls
• Discover the must-have details for roof diaphragms and their connections to the walls
• Work through a number of design examples

Webinar Outline

• Introduction
• Design standards for lateral-force resisting systems in wood-framed buildings
• Rational design vs. conventional construction
• Components of a wood-frame lateral-load resisting system
• Load path for resisting lateral loads
• Design of diaphragms
• Design of shear walls
• Conclusion, final Q&A

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
