2017 ISEA Spring Conference

Design of Wood Connections Using the NDS and TR12

This course will feature techniques for designing connections for wood members utilizing AWC's 2015 National Design Specification® (NDS®) for Wood Construction and Technical Report 12 - General Dowel Equations for Calculating Lateral Connection Values (TR12). Topics will include connection design philosophy and behavior, an overview of common fastener types, changes in the 2015 NDS related to cross-laminated timber, and design examples per TR12.

Learning Objectives:

1. Be familiar with current wood member connection solutions and applicable design requirements.
2. Be familiar with Technical Report 12 and provisions for connection design beyond NDS requirements.
3. Be able to recommend fastening guidelines for wood to steel, wood to concrete, and wood to wood connections.
4. Be able to describe effects of moisture on wood member connections and implement proper detailing to mitigate issues that may occur.

Tall Wood Structures: Current Trends and Related Code and Standard Changes

Cross-laminated timber (CLT) has been in use worldwide for over 15 years, but most notably in Europe. Building with CLT has increased in popularity for many reasons including: just-in-time fabrication and job site delivery, speed and efficiency in construction, reduced job site noise and on-site labor force, substitution of high embodied materials with a renewable resource that sequesters carbon, and creating a living or work space that has the aesthetics of exposed wood. 

The recent introduction of CLT in the 2015 National Design Specification® for Wood Construction (NDS®) and the 2015 International Building Code has opened up an exciting new chapter in wood construction.  The use of CLT alone or in combination with other mass timber elements, such as glued laminated timber (GLT), nail laminated timber (NLT), or structural composite lumber (SCL), is becoming more common in buildings complying with the current code.  There is also an effort underway by the International Code Council (ICC) to recognize the use of mass timber elements in taller, combustible construction through the work of the ICC Tall Wood Ad Hoc Committee. This presentation will provide an introduction to CLT including relevant design standards and code references. Examples of various mass timber buildings around the world will be provided and potential future code provisions relating to mass timber will also be discussed.

Learning Objectives:

1. Be able to define cross-laminated timber
2. Be aware of code and standard updates relevant to CLT and other mass timber elements
3. Be aware of notable mass timber structures around the globe
4. Learn about current tall wood building projects and resources

Lori graduated from Penn State University with a BS in Civil Engineering, and from Clemson University with an MS in Civil Engineering. Upon graduating from Clemson, Lori was employed as a forensic structural engineer with SK&A in suburban Washington, DC. She then enrolled at Virginia Tech where she earned a Master of Forestry degree in the Department of Wood Science and Forest Products (now called the Department of Sustainable Biomaterials). Her research at Virginia Tech involved connections for fall-protection harnesses for residential roofers and construction workers. After graduating from Virginia Tech, Lori joined the American Wood Council in Leesburg, VA. Her work as Manager of Educational Outreach at AWC includes handling helpdesk inquiries, outreach and educational opportunities, and other technology transfer activities regarding the use of wood in safe and sustainable buildings. She is a licensed PE in Virginia.
