Seismic retrofitting of reinforced concrete (brick, stone) structures

The use of an external carbon fiber reinforcement system in earthquake-prone areas with a seismicity level of 7–9 points makes it possible to reduce the seismic load by 1.5–4 times, depending on the design of the facility and site conditions.

Benefits of seismic retrofitting using composite materials

Seismic retrofit of buildings using carbon fiber decrease the cost of such projects by 5- 20% in comparison with traditional methods of seismic retrofit (RCC Jacketing, reinforced concrete, construction of extra reinforced concrete and metallic frames, … etc.). Price variation depends on the number of floors in the building being strengthened, its structural elements, and the seismic area

Seismic retrofit with carbon fiber reduces the cost of operating the facility, because the life-time of this system is at least 50 years.

The use of carbon fiber allows architects to freely choose a planning solution, and provides engineers with a wide selection of structural solutions for the construction, as well as reducing the load on the structure.

The absence of thickening of the building elements, strengthened with carbon fiber, preserves the existing architectural appearance.
