Carbon Fiber-Based Material Can Prevent Thousands of Buildings During a Future Major Earthquake


Yalova, Turkey – Today a team of structural experts from industry and universities in Turkey demonstrated in a side-by-side test how a building retrofitted with carbon fiber composites can successfully survive a simulated earthquake.

A carbon fiber and composites company based in Yalova  joined with Istanbul Technical University to conduct a simultaneous full-scale earthquake simulation at a site in Yalova using  carbon fiber reinforced polymer (CFRP) technology.  The testing site is near the epicenter of one of Turkey’s deadliest earthquake disasters that in 1999 cost more than 18,000 lives.  Today the team of experts were very satisfied by the ability of the upgraded structure to withstand a simulated severe seismic shock, and will review detailed data collected during the test to improve survivability and limit property damage in future earthquakes.


Using the same foundation and materials, both buildings were constructed using practices that were common for several decades in Turkish construction, prior to implementation of new requirements under the Earthquake Regulations of 2007.  The first building was retrofitted with CFRP, a high-strength, light weight and affordable technology developed by experts.  The second building was not changed. The experiment’s goal was to demonstrate how a conventional building can be retrofitted to withstand strong seismic forces.

After several days of final site preparations which included extensive placement of advanced sensors, the test was completed under the supervision of Professor Doctor Alper İlki from Istanbul Technical University using a system of hydraulic actuators to simulate a seismic shock. This is the first test in the world of its type to simulate seismic forces on two 3-story structures.  According to Professor İlki: “Into my best knowledge, this is one of the largest and exemplary collaborations of industry, academia and the local government in the field of Structural and Earthquake Engineering in Turkey. 96,796 houses and 15,939 businesses were destroyed. The reason I’m telling all this is to specify the meaning of realizing this project here in Yalova . Yalova where most of our colleagues and their families live. That’s why I would like to express my gratitude to our Governor for providing this site to us for the test.”


CFRP composites have tensile strength higher than steel, are lightweight and do not corrode.  Beyond Materials carbon fiber wrap is designed to offer this critical technology that can be quickly and efficiently applied by properly trained construction professionals, usually without interrupting the daily functions of the structures. Unlike traditional retrofit or reconstruction techniques that require demolition and reconstruction of part or all of failing structures, carbon fiber goes right over the existing substrate. This minimizes disruption during repair and saves significantly on installation time and costs. Applied in the form of a flexible fabric during installation, it is then saturated with a resin matrix, allowing it to harden to a strong, unyielding material with a strength-to-weight ratio that exceeds fifty times that of steel.
