With mass-timber structures gaining momentum in the U.S., ENR takes a look at some of the largest wooden structures in the world and the future of lumber-based construction.

Performance-based structural fire design of steel frames can eliminate fire protection on up to half of a building’s floor beams, according to a two-year study of PBSFD.

A slow recovery has begun following economic fallout caused by COVID-19

Airports, highways and civic structures are testbeds for patented technology that uses titanium dioxide to capture pollutants, particularly nitrogen oxides, in pavements—creating “smog-eating roads.”

The American Wood Council and International Code Council have released a joint publication, Mass Timber Buildings and the IBC, which gives an overview of code changes regarding mass timber construction.

A Canadian company’s “smog-eating” highway noise wall technology, aimed at trapping air pollutants emitted by vehicles, is currently being tested on highways in Toronto and the U.K. Proponents say it can reduce overall air pollution by 50%.

Flood design is often reduced to meeting federal and local regulations, but some engineers want more bespoke solutions to keep buildings dry

The New York City Dept. of Buildings has granted permission to use SpeedCore in New York City. The high-rise lateral-load resisting system of tied dual-plate wall modules field-filled with concrete has the potential to slash superstructure construction time compared to steel frames with reinforced concrete cores.

Domestic fabricators applaud the decision, while manufacturers, some contractors had hoped for relief

There is good news for boosters of a modular system of tied dual-plate walls field-filled with concrete—dubbed SpeedCore for its potential to slash superstructure construction time compared to steel frames with reinforced concrete cores.
