The new 25-foot tall reaction wall and 60-by-80-foot strong floor at the A.A. “Red” Emmerson Advanced Wood Products Lab will be used for large scale testing of mass timber assemblies and building systems, including three-story systems in Arijit Sinha’s upcoming lateral design research.  

 

CORVALLIS, Ore. – TallWood Design Institute (TDI) has announced the 2019 recipients of new research funding under its annual call for proposals funded by the Agricultural Research Service (ARS). The program focuses on applying interdisciplinary scientific expertise to address current opportunities and challenges in contemporary wood construction. A total of $1.2 million dollars was awarded to eight research projects, with themes including structural validation of timber building systems, fire performance of connections, durability of bond lines and innovative timber manufacturing.

“We are thrilled to be continuing our partnership with the Agricultural Research Service and bringing the faculty expertise and enhanced facilities of Oregon State University and University of Oregon to bear on these important research questions” says TDI Director Iain Macdonald.

Many of the projects will utilize enhanced capabilities offered by the A.A. “Red” Emmerson Advanced Wood Products Laboratory at Oregon State University, which opened in spring 2019.

 

2019 Major Awards:

Mass Plywood Panel (MPP) Concrete-Composite Floor Systems
Andre Barbosa, School of Civil and Construction Engineering, Oregon State University
This research will generate benchmark data to characterize the performance of concrete-composite mass plywood panel (MPP) floors through multi-scale testing of novel shear connectors, MPP floor elements and full-scale floor systems, including MPP-to-glulam connections.
 
Fire Performance of Timber Beam-to-Column Connections
Erica Fischer, School of Civil and Construction Engineering, Oregon State University
This project will help the design and research communities gain a better understanding of the structural performance of timber connections during fire and post-earthquake fire conditions, and will generate benchmark data to create flexible models for future design of connections.

Design, Construction and Maintenance of Mass Timber Post-Tensioned Shear Walls
Mariapaola Riggio, Department of Wood Science and Engineering, Oregon State University
This research will characterize and validate the long-term performance of cross-laminated timber (CLT) and veneer-based post-tensioned rocking shear wall systems, in terms of their response to climate, moisture, dimension changes and tension loss, in order to generate guidelines to inform design and maintenance of such systems. 
 
Innovative Lateral Systems for Mass Timber
Arijit Sinha, Department of Wood Science and Engineering, Oregon State University
This project will generate benchmark data characterizing the performance of multiple innovative mass-timber shear wall systems [ISM1] from the scale of connectors to full-scale building systems up to three stories. This work will lay the foundation for upcoming six-story and ten-story mass timber seismic shake table tests, part of a multi-organization research initiative.
 
Mass Plywood Panels: Performance, Design, and Application
Fred Kamke, Department of Wood Science and Engineering, Oregon State University
This project will augment existing research to characterize the mechanical performance of MPP. This research will also characterize the heat and moisture performance of MPP and correlate the effects of climate and material conditions during the manufacturing process and in service to bond performance and mechanical performance.
 
2019 Discovery Awards:

Convergent Craft: Mass Timber Building Culture for the 21st Century
Mark Donofrio, School of Architecture and Environment, University of Oregon
This research project examines the convergence of advances in engineered mass timber products and digital design tools across the globe, and will culminate in the design and fabrication of a timber structure using state-of-the-art digital techniques.
 
Acoustical Field Testing of Mass Timber Buildings
Kevin Van Den Wymelenberg, School of Architecture and Environment, University of Oregon
This research will augment recent data from acoustic lab testing of mass timber floor and wall assemblies by conducting in-field testing of the acoustic performance of several newly-constructed mass timber buildings and by collecting occupant feedback on acoustic comfort.
 
Mass Timber Fire Research and Design Guideline
Erica Fischer, School of Civil and Construction Engineering, Oregon State University
This project involves the development of a comprehensive mass-timber research and design guide focusing on fire science and engineering, spanning research and building code development across multiple countries and framing developments in North America. Additional funding for this project is provided by Codes Unlimited.

 

The Kuka robot at the Emmerson Lab will be used alongside the Biesse Uniteam UT9 CNC machine and other advanced manufacturing equipment to explore advanced digital design and fabrication techniques in timber construction, the focus of Donofrio’s “Convergent Craft” project.
