EXPERIMENTAL  STUDY  OF  SEISMIC  RETROFITTING  USING  EXTERNALLY  BONDED  FIBER  REINFORCED  POLYMERS 

The paper presents the results of investigation of the external reinforcement using carbon fiber-based materials (carbon tape and mesh) affecting the load-bearing capacity of masonry under diagonal static load. The behavior of reinforced specimens is ascertained as well as the quantitative characteristics of the external reinforcement that have an effect on the load-bearing capacity of masonry. The calculation procedure is described for the load-bearing of masonry strengthened by composite materials.

Keywords: masonry; seismic reinforcement; external reinforcement; carbon fiber; carbon tape; carbon mesh.
