Concrete is incredibly strong in compression - but very weak in tension. That’s why engineers add reinforcement. In this video, I explain why reinforcement is needed, how rebar helps, and how ...

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 ...

When natural disaster strikes, a building’s survival often depends on how it’s built. Engineers at Carnegie Mellon University have created a fast, highly accurate simulator for spray-based concrete 3D ...

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 ...

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 ...

In what’s become almost an annual rite of passage, concrete contractors at various industry conferences show me “war wounds” that have resulted from wire mesh and rebar (reinforcement bars). They wear ...

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 ...
