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.
Six months after an explosion and fire destroyed a grid-connected energy-storage battery facility in Surprise, Ariz., investigators are still trying to figure out all that happened.
Based on recent fire test results, mass timber groups have adjusted product certification standards to require the use of cross-laminated timber with structural adhesives tested to demonstrate better fire performance.
Successful performance in fire tests of three types of off-the-shelf metal connectors for glue-laminated-timber column-to-beam assemblies will make it easier for designers to get approval for GLT structural systems in buildings up to 85 ft in height, says the Softwood Lumber Board, which sponsored the tests.
Good performance of the cross-laminated timber panels, made by the first certified CLT supplier in the U.S., is expected to have a positive impact on domestic production.
