A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that link openings in concrete shear walls—to reduce rebar congestion.
Concrete’s large carbon footprint—that is, the amount of carbon dioxide emitted during the cement manufacturing process—is estimated to be 5% of industrial CO2 emissions, a source of concern in the battle against human-caused climate change.
Moving from the lab to the field, a highway off-ramp bridge under construction in Seattle features memory-retaining metal rods and bendable concrete designed to provide the structure with flexibility sufficient to withstand a major seismic event.
During this webinar, ENR will chat with beta testers and early adopters to find out what’s available in the way of wearable technologies for the jobsite of today, and what’s in store for the jobsite of tomorrow.
ENR will talk to contractors who have been engaged in this debate for years now through project after project to hear what they have learned, why they have transitioned operations from ink to digital, and how they set up new systems for success.
In this webinar, discover how that 15% wait time can be significantly reduced with construction technology that focuses on efficiency gains and higher labor productivity made possible with automation of people, process, and technology.
