Continuing Education for the Practical Structural Engineer:

Cross-Laminated Timber (CLT): What Wood You Like To Know WEBINAR SERIES OF 2 PRESENTATION TOPICS April 22 & 29 | 11 a.m. - Noon (EDT) 2.0 SEAMASS PDHs or 2.0 NCSEA Diamond-Certified PDHs Available

There has not been a hotter topic in construction than CLT, which offers sustainability, good looks and structural integrity to building projects. This is your opportunity to learn about CLT from experts in wood construction, and to see some of the practical lessons learned from a recently built project.  Our presenters will share practical applications for CLT, including new Code provisions, design examples, and a large local project that incorporates CLT design. Register today and take advantage of this opportunity to expand your knowledge about this innovative engineered wood product.

PRESENTATION TOPICS & OVERVIEWS

APRIL 22: CLT Diaphragm Design: New Code Provisions & Design Examples Presenter: Scott Breneman, Ph.D, PE, SE, M.ASCE Sr. Technical Director/Mass Timber - WoodWorks Wood Products Council

PRESENTATION OVERVIEW: The use of cross-laminated timber (CLT) as structural floor and roof panels has seen incredible growth in the US over the past decade. However, its use as part of a seismic and wind force-resisting system—either as a diaphragm or shear wall—has not been codified to date. This has resulted in designing CLT diaphragms through alternative means or using a structural topping, such as a layer of wood structural panels or concrete, as the diaphragm.  This webinar will introduce new provisions for CLT diaphragm design, in the American Wood Council’s 2021 Special Design Provisions for Wind and Seismic (SDPWS), which will be the code-referenced standard to provide guidance on CLT diaphragms. Following a discussion of the new SDPWS provisions, CLT diaphragm detailing options and design examples will be presented in order to apply practical design techniques and discuss structural detailing challenges and solutions.

APRIL 29: CLT Design: The Olver Design Building at University of Massachusetts Amherst Presenter: Jeffrey D. Langlois, Sr. Project Manager - Simpson Gumpertz & Heger

PRESENTATION / PROJECT OVERVIEW: One of the largest mass timber buildings in the U.S. and a first of its kind in the Northeast, the 87,500 S.F. John W. Olver Design Building on the Amherst campus of the University of Massachusetts uses wood products in new and creative ways.  SGH collaborated with Equilibrium Consulting Inc. to design this innovative structure. By exposing the engineered timber framing, cross-laminated timber (CLT) decks, and concrete slabs, the project team emphasized the structure’s contribution to the building’s design and minimized the need for many interior finishes.  Structural design highlights include: Glue-laminated timber beams, columns, and braced frames CLT decks composite with concrete slabs and CLT bearing and shear walls around mechanical and stair/elevator shafts A system of three-dimensional roof trusses – consisting of composite concrete-glulam chords, round glulam compression struts, and steel tension ties – to span over the multistory atrium Full-story steel truss to support the atrium truss system and suspended CLT stairway below SGH load tested connection mockups to evaluate their strength and ductility. SGH also prepared documentation to demonstrate this innovative structural design meets the general intent of the current Massachusetts State Building Code.

ABOUT THE PRESENTERS

Scott Breneman, Ph.D, PE, SE, M.ASCE Sr. Technical Director, Mass Timber - WoodWorks Dr. Breneman is the Senior Technical Director of the Architectural and Engineering Solutions Team of WoodWorks Wood Products Council. Scott has experience with structural design and peer review of projects varying from single-family homes to high-rise hospitals, the seismic rehabilitation of institutional buildings, and advanced analysis and technology development. At WoodWorks, Scott provides project support to architects, engineers and other professionals designing buildings, oversees the development of technical educational content and educates designers on effective use of wood framing systems.

Dr. Breneman is a member of ASCE and SEI, a past President of the Structural Engineers Association of Central California, a past Director of the Structural Engineers Association of California, and an Associate Member of the Seismic Subcommittee of ASCE 7-16 Minimum Design Loads for Buildings and Other Structures and a member of the ANSI/APA PRG 320 2017 update committee. He earned his bachelor's and master's degrees from the University of Florida and a doctorate from Stanford University. His doctoral research entailed novel methods to reduce seismic damage to mid-rise and high-rise buildings.

Jeffrey D. Langlois Sr. Project Manager - Simpson Gumpertz & Heger Jeff Langlois is a member of Simpson Gumpertz & Heger Inc.’s Structural Engineering group. He has more than 14 years of experience managing projects involving design, investigation and rehabilitation of structures of all types with a focus on light-frame wood and heavy timber construction.  His specialty skills include design of buildings employing engineered wood components, structural evaluation of existing wood structures, in situ visual grading and determination of design properties for existing heavy timber components, and investigation of dimensionally distressed or discolored architectural millwork.

He oversees design of construction documents and provides construction phase services for projects ranging from small adaptive reuse fit-outs, to multi-story new construction.
