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 ...

Roughly 11,000 kilometers of GFRP rebar reinforce this concrete flood mitigation channel in Jizan, Saudi Arabia, and enable its 100-year service life. Photo Credit for all images: Mateenbar Worldwide, ...

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 ...

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 ...

Nearly 40% of failure of concrete structures occurs due to corrosion of embedded steel reinforcement. For this reason, corrosion control of steel reinforcement is essential to prevent damage and ...

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 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 ...

The project conducted a series of experiments to investigate residual bond strength between rebar and concrete after exposure to high temperatures. A total of 15 beam-end specimens based on ASTM A944 ...

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 ...
