Offset Diaphragms and Shear Walls
Terry Malone, PE, SE, WoodWorks
Several decades ago, residential and commercial buildings were fairly straight forward redundant structures with reasonable layouts of the lateral force resisting system. Present day structures are much more complex, which incorporate multiple horizontal and vertical offsets in the diaphragms, multiple irregularities, and fewer lateral resisting elements. This two part presentation will provide a brief review of a method used to analyze these complex structures.
Part I: Topics will include code requirements, how to recognize diaphragm irregularities and discontinuities, how shears are distributed through complex diaphragms, the method of analysis used to solve the transfer of forces across areas of discontinuity, and the analysis of flexible wood sheathed or untopped steel decking diaphragms with horizontal offsets.
Part II: This session will cover how to conduct a preliminary breakdown of a complex diaphragm to better understand the distribution of forces and assure that complete load paths are being established. Examples will be provided illustrating how to analyze in-plane and out-of-plane offset shear walls that are typically created by these diaphragms.
Terry Malone is a licensed structural engineer in Washington, Oregon and Arizona. Prior to joining WoodWorks, he was a principal in consulting structural engineering firms in Washington and Oregon, conducted third-party structural plan reviews and has served as a faculty member at St. Martin’s College in Lacey, Washington. Terry has over 35 years of wood design experience and has taken an active role as a presenter providing seminars at state and local ICC chapters and professional engineering organizations. Terry is author of The Analysis of Irregular Shaped Structures: Diaphragms and Shear Walls, published by McGraw-Hill and ICC. He is a member of the Structural Engineers’ Association of Arizona and the International Code Council.
Seismic Design of Wood Structures in the Context of Building Codes and Standards
Michelle Kam-Biron, PE, SE, SECB, M. ASCE, Director of Education, American Wood Council
This presentation highlights 2012 International Building Code (IBC), 2010 Minimum Design Loads for Buildings and Other Structures (ASCE 7-10) and 2008 Special Design Provisions for Wind and Seismic (SDPWS) requirements applicable to the seismic design of wood structures. Code considerations related to wood-frame shear walls and diaphragms are discussed, including failure modes of wood shear walls and the detailing required to provide ductile behavior. Topics will also include limitations on the use of wood in seismic design, changes to the 2015 SDPWS from previous codes and standards, and additional resources.
Michelle Kam-Biron is a California licensed structural engineer and Director of Education for the American Wood Council (AWC) where she oversees and develops continuing educational resources related to structural wood for architects, engineers, and code officials. Prior to joining AWC, she worked for nearly five years in the wood industry as the Senior Technical Director – National Lead Mid-rise/Multi-family Construction for the Wood Products Council initiative WoodWorks. She also has over 20 years of experience managing, designing and plan reviewing a wide range of projects of various structural materials. Ms. Kam-Biron graduated from Cal Poly, San Luis Obispo with a BS in Architectural Engineering and is President-elect of the Structural Engineers Association of Southern California.
