Type III Fire-Resistant Design & Detailing: Exterior Walls, Intersections & Balconies

With an increase in mid-rise wood-frame buildings, more designers are seeking information on code-compliant and constructible detailing. Many are unsure of the code's requirements for details, specifically at the intersection of rated assemblies and where structure and fire protection meet.
This session will focus on common detailing issues and areas of misunderstanding of exterior walls and their intersection with rated floor assemblies. Join us for a review of mid-rise wood-frame opportunities and code-specified building sizes. Plus, review detailing code requirements, code compliance, and rationale for approval with an emphasis on constructability and practicality.


Learning Objectives

  1. Compare type II and type III construction with regard to cost, building size, and fire resistance per the International Building Code.
  2. Review requirements for exterior walls along with common questions about the use of asymmetric assemblies, allowance of wood structural panels, and bearing vs. non-bearing requirements.
  3. Examine various floor-to-exterior wall details for use in wood-frame, Type III construction, and discuss code compliance paths and approval rationale for each.
  4. Explore detailing requirements for balconies.
