Carbon fiber manufacturer DowAksa (Istanbul, Turkey) and Istanbul Technical University (ITU) have simulated an earthquake to demonstrate the ability of DowAksa's material to lend strength to buildings in earthquake-prone regions.

In a seismically active area hit hard by previous earthquakes, a team of Turkish experts spent more than six months preparing a test site and erecting two identical structures (in terms of material qualities, geometry and reinforcement). Both structures were constructed to common (but outdated) building codes resembling thousands of dwellings in Turkey with low concrete strength, weak-column/strong-beam configuration and transverse reinforcement deficiencies. 

The first building was typical of hundreds of thousands of houses in the country that do not have a strengthening system, while the second building's columns were were treated with an external wrapping of DowAksa's carbon fiber composites systems.

Over a three-day period, the structures were simultaneously subjected to simulated seismic loading to deliver forces replicating a magnitude 6.0-plus (Richter Scale) earthquake. Once the test approached seismic forces of approximately a magnitude 6.5 earthquake, the untreated building suffered a catastrophic collapse. The carbon fiber-supported building withstood lateral drift 10 times greater and outlasting the shake.
