STD401-2 – AWC's 2008 Special Design Provisions for Wind and Seismic ASD/LRFD – Part 2: Diaphragm Deflection Calculations


YouTube SelfStudy Subjects

Per the International Building Code (IBC), structures using wood shear walls and diaphragms to resist wind, seismic and other lateral loads shall be designed and constructed in accordance with AWC's Special Design Provisions for Wind and Seismic (SDPWS). Calculation of wood-frame diaphragm deflection should account for bending and shear deflections, fastener deformation, chord splice slip, and other contributing sources of deflections. The 2008 SDPWS incorporates both a 3-term and 4-term deflection equation that accounts for these variables. This course will provide an overview and comparison of the 3-term and 4-term deflection equations. Additionally, an example showing calculation of mid-span deflection of a blocked wood structural panel diaphragm will be presented.

Learning Outcomes:

Upon completion of this course, participants will:

  1. Be able to calculate wood-frame diaphragm deflection using the 2008 SDPWS.
  2. Be able to compare the difference between the 3-term and 4-term deflection equation in the 2008 SDPWS.
  3. Be able to analyze individual components of the deflection equations to determine their magnitude of impact on total deflection.
  4. Be able to utilize the example deflection calculation in future design work as a model for their own calculations.
  5. NCSEA does not warrant that a program complies with the continuing education requirements in all jurisdictions.
