PSU tests new green wood’s seismic strength

Via Portland Tribune Jennifer Anderson January 3, 2017 When the 12-story Framework building planned at Portland’s Northwest 10th Avenue and Glisan Street is complete, it may look to passers-by like any other Pearl District condo tower. Designers and engineers across the country are chasing an innovative style of mass timber construction pioneered in Europe, which they believe will go a long way to reduce the carbon footprint of large buildings.But it will hold a special distinction in the sustainable building world: the nation’s tallest building made primarily from mass timber (long pieces of timber, glue-laminated together). The breakthrough came with the development of cross-laminated timber or CLT: Large, layered

Mass Timber Assemblies Earn New Fire Rating

As the first U.S. certified manufacturer of Cross-Laminated Timber (CLT), D.R. Johnson (DRJ) is dedicated to showing the benefits of using this innovative building material. To accomplish this, DRJ has partnered with many academic institutions and industry leaders to showcase CLT and glulam’s ability to withstand everything from seismic events to fire blasts. Most recently, DRJ joined the Softwood Lumber Board, Arup and MyTiCon to participate in fire testing of glulam beam-to-column connectors in Type IV construction. The lack of an “off-the-shelf” fire rated solution for glulam beam-to-column connectors was a barrier to medium-rise mass timber construction. Several successful fire tests existed, but none specifically for this implementation. The

Rising CLT at University of Oregon

University of Oregon is in the process of building their Knight Campus for accelerating scientific impact in Eugene, Oregon. The first if DRJ mass timber to be implemented into U of O’s campus was for their redesigned canopy at Hayward Field. It was the first of many deliveries that will be making its way from our DRJ plant in Riddle, Oregon. The University of Oregon is looking to build more with mass timber in order to create a sustainable campus for students. The director of design at UO and Oregon State University collaborative TallWood Design Institute, Sheine, said that the campus mezzanines will be built from the mass timber
