New Code Provisions for Tall Timber Structures in California

May 9 @ 4:00 pm - 5:00 pm PDT

  • In Person
  • Online

Regional Online & In-Person Event (San Francisco, CA)

As awareness of mass timber’s potential for tall wood structures has grown, there has been a push among U.S. building designers to achieve greater heights with these materials. Initially, tall wood buildings in the U.S. were proposed using international examples as precedent, with a project-specific performance-based

design approach used. However, a uniform set of tall wood code provisions has begun going into effect in many States with adoption of the 2021 International Building Code (IBC), which will allow up to 18 stories of mass timber construction.

The 2022 California Building Code (CBC) has now also been adopted with a series of tall wood code changes based on the new IBC provisions, but with California specific modifications. Following a brief discussion of history and motivators, this presentation will introduce the new IBC and CBC tall wood code provisions, as well as the technical research and testing that supported their adoption.
