Mass Timber Construction: Products, Performance and Design

MARCH 4, 2019 - The meeting WILL be held in Framingham, as scheduled!

Mass Timber Construction: Products, Performance and Design

Presented by Marc Rivard, PE, SE of WoodWorks

Due to their high strength, dimensional stability and positive environmental performance, mass timber building products are quickly becoming materials of choice for sustainably-minded designers. This presentation will provide a detailed look at the variety of mass timber products available, including glue-laminated timber (glulam), cross laminated timber (CLT), nail laminated timber (NLT), heavy timber decking, and other engineered and composite systems. Applications for the use of these products under modern building codes will be discussed, and examples of their use in U.S. projects reviewed. Mass timber’s ability to act as both structure and exposed finish will also be highlighted, as will its performance as part of an assembly, considering design objectives related to structural performance, fire resistance, acoustics, and energy efficiency. Recent code changes for the 2021 IBC will also be discussed, including the fire testing that supported them.

Mr. Rivard is a licensed Structural and Professional Engineer in California, Massachusetts and New Hampshire, and received his BS in Civil and Environmental Engineering from UMass Amherst. Prior to WoodWorks, he was a Senior Structural Engineer involved primarily with seismic design and analysis of new and existing buildings. Marc has experience providing structural calculations, plans, specifications, construction administration and structural plan review services for a wide range of building types, including multi-family/mixed-use, education, commercial, office, institutional, and military.
