This course is an overview of the many framing systems commonly used in buildings in the United States for a variety of span lengths.  The presentation will review the possible wood structural framing systems including rafters, metal plated wood trusses, engineered wood products and hybrid roof systems.  Also covered will be how these components can be combined to create efficient and versatile roof framing systems. All of these concepts will be reinforced through the presentation of real example projects with details on the framing system used to achieve the project goals.

About the Presenter:

A California licensed professional engineer, Janelle Leafblad, Allied Member, has been an active building technology consultant since 2002, primarily in the areas of wood technology, investigation and design of building envelope components, and construction for both historic and contemporary structures. She earned her BS in Architectural Engineering from the Milwaukee School of Engineering and her MS in Wood Science and Technology from the University of California at Berkeley

Learning Objectives:

  1. Participants will be familiar with wood framing options available for use as roof framing and be able to evaluate different framing systems to use for building projects.
  2. Participants will be familiar with the variety of roof geometries that are possible with wood framing systems.
  3. Through the presentation of several project case studies, the participant will understand how long span roof systems can be built from all wood and hybrid wood structural configurations.
  4. Participants will be familiar with the International Building Code provisions that allow the use of wood systems in many roof applications including use in non-combustible Type I and Type II construction buildings.
