Purpose and Background

This webinar highlights 2015 International Building Code (IBC), 2010 Minimum Design Loads for Buildings and Other Structures (ASCE/SEI 7-10) and the 2015 Special Design Provisions for Wind and Seismic (SDPWS) requirements applicable to the seismic design of wood structures. It discusses deflection equations, detailing requirements, the limitations of using wood in seismic design, and changes from previous codes and standards.

Primary Topics of Discussion

• Wood-frame shear wall and diaphragm code issues
• Deflection equations
• Detailing requirements
• Limitations on the use of wood in seismic design
• Changes from previous codes and standards
• Additional resources

Learning Outcomes

• Discuss ASCE/SEI 7-10 seismic provisions for the design of wood structures
• Analyze AWC’s SDPWS seismic provisions for the design of wood structures
• Identify the limitations of wood shear walls and diaphragms
• Explain special seismic shear wall and diaphragm detailing requirements for wood structures

Webinar Benefits

• Become familiar with important sections of the 2015 International Building Code, ASCE/SEI 7-10, and SDPWS standards of design for structural wood lateral force resisting systems
• Learn about the background behind the significant seismic code provisions related to wood lateral force resisting systems
• Discuss key design considerations that must be considered to ensure the structural performance of wood framed structures with wood shear walls and diaphragms
