Most slabs-on-ground are unreinforced or nominally reinforced for crack-width control. When positioned in the upper or top portion of the slab thickness, steel reinforcement limits the widths of ...

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 ...

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 ...

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 ...

It's tempting to think of "strength" as a simple variable and that various materials all fall somewhere on a spectrum of strong to weak. The reality, of course, is much more complex. Different ...

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 ...

The use of structural metal as a grounding electrode is an issue that has been revised during several recent Code cycles. The 2011 NEC has once again revisited the rule explaining when a structural ...

Rebar is the hidden backbone of most concrete structures, but its tendency to rust can cause major problems over time. This video explains how rebar corrosion happens, why concrete usually protects ...

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 ...

Concrete is crumbling on the Cross County Parkway in Westchester, revealing metal reinforcement called rebar that is not supposed to be exposed to the elements. The highway hazard has drivers very ...
