Rise Of Mass Timber Buildings Showcase Its Increasing Credibility

New mass timber products are becoming more widespread and encouraging builders, designers, and engineers to search for the best applications for mass timber initiatives. A few of the mass timber building products available today include:
• Cross-laminated timber
• Nail-laminated timber
• Glue-laminated timber
• Dowel-laminated timber

As they test the capabilities of these materials, designers are looking to existing mass timber buildings around the world for examples and inspiration.

Canadian and European researchers and architects began experimenting with the design of mass timber buildings in the 1970s. European timber projects have shown that weight matters with structural systems, and mass timber structures weigh up to one-third as much as their concrete counterparts. This fact has made wood construction a viable prospect in places where building height and weight are limited, such as city utilities, subway tunnels, and underground rail yards.

Due to their lighter weight, mass timber buildings are more resilient in seismic zones. They carry less inertia, so the possibility of destructive swaying goes down. This approach was recently applied in the Brock Commons tower, an 18-story college residence designed for the University of British Columbia by Canadian firm Acton Ostry Architects.

The 173-foot-tall tower combines glue-laminated columns, cross-laminated timber floor slabs, dual concrete cores, and steel connectors. The cores help to counteract wind-generated and seismic forces while anchoring the mass timber building in place. It meets structural and fire-safety regulations by utilizing a specially designed set of interdependent finishes and building materials.

World’s Tallest Timber Building Topped Off Ahead Of Schedule

In Vancouver, Canada, the towering timber Brock Commons just had its final panel installed, making the dream of the world’s tallest timber building a reality, reports the website Inhabitat.

In just 66 days – ahead of the original scheduled timeframe – the exterior of the Acton Ostry Architects‘ record-breaking design has come to fruition, which could bump up the projected fall 2017 completion date to next year’s spring semester. The final panel of the University of British Columbia student housing structure was lifted and installed earlier this month.

John Metras, managing director of UBC Infrastructure, said, “Construction just went really smoothly. It was well designed and the construction sequence went smoothly.”

Construction began last November, followed by the erection of the building’s freestanding concrete cores earlier this year.

To ease fire safety fears of an 18-story timber structure, Brock Commons is outfitted with a sprinkler system and the wood is encapsulated in drywall and concrete. The lighter weight of the building also allows for better energy dissipation during an earthquake, making it proficient at withstanding all kinds of disasters. Students will be able to move in next year, quite possibly in the spring semester.
