Bonding the composite material.

A research team from West Virginia University (WVU) has developed a system making use of composite materials that could improve earthquake resistance in buildings.

WVU professor Hota GangaRao and Praveen Majjigapu, a PhD student in civil engineering, say that the system could increase the strength and endurance of structures in earthquakes, hurricanes, tornadoes and other large blasts.

The three-piece system consists of filler modules (wedge-like parts made to certain specifications) reinforcing dowels and composite materials. The composite material, incorporating fabric made of carbon or glass fibers bonded with a polymer resin is wrapped around concrete, adhered with additional resin and left to cure. 

‘With this system, even if a joint cracks under excessive loads it won’t immediately collapse,’ said GangaRao, professor of Civil and Environmental Engineering.
