When concrete contractors need rebar cut or bent, they have three choices. They can have a fabricator pre-cut or pre-bend the rebar to the specs. They can have their crews use manual tools to hand cut ...

Concrete makes up a huge part of the built world, but steel rebar–reinforced concrete is difficult and dangerous for humans to make. Toggle thinks robots can make it faster and safer. (Courtesy Toggle ...

If structural engineers have their way, building codes will take a leap forward in the next couple of years to allow the use of higher-strength 80-ksi reinforcing steel in concrete shear walls in high ...

The Fiber Reinforced Polymer (FRP) rebar industry is about thirty years old. The industry started by molding aramid and carbon fibers with various thermoset resins, and then expanded to glass fibers ...

Morteza Khatib, a Ph.D student at the University of Miami, shows off a photo of the Fate Bridge on the university's Coral Gables campus. The bridge is built with glass-based rebar. "I was always ...

While many of us might think that concrete structures such as bridges simply stand unaided for decades at a time, the fact is that they require maintenance as often as once every five years. An ...

Standing before a crowd of curious onlookers at a corner of the show floor at the World of Concrete trade show in Las Vegas, Advanced Construction Robotics president and cofounder Jeremy Searock made ...

A corrosion-free composite rebar-reinforced floor slab, based on a lab-tested glass fiber-reinforced polymer rebar-specific punching shear equation, which performs like a steel-reinforced slab at a ...

The proposed rapid evaluation framework is trained based on a large number of samples from the database and drawing tests. The characteristics of the bonding stress-slip constitutive are learned using ...
