About the event

This regional in-person technical seminar examines fire-resistant design principles for mid-rise wood-frame buildings under the International Building Code. The session addresses frequent detailing challenges and misunderstandings concerning exterior walls, rated floor assembly intersections, and mechanical, stair, and elevator shafts. Instruction covers code-specified building sizes, asymmetric assemblies, wood structural panels, bearing versus non-bearing configurations, and approval rationale focused on practical constructability. The event concludes with an on-site networking happy hour where attendees can connect with peers and discuss code compliance paths for Type III wood construction projects.

What you’ll learn

  • Review Type III construction with regard to cost, building size, and fire resistance per the International Building Code.
  • Review code requirements for exterior and shaft walls, emphasizing common questions, including the use of asymmetric assemblies, allowance of wood structural panels, and bearing vs. non-bearing requirements.
  • Examine a variety of floor-to-exterior wall and floor-to-shaft-wall details for use in wood-frame, Type III construction, and discuss code compliance paths and approval rationale for each.
  • Recognize structural design considerations for stair and elevator shafts.

Attendance notes

Following the presentation, an on-site networking happy hour will be held.
