Columns/piers are the most important structural element in buildings and bridges. A great number of structural failures are attributed to column failure, especially those constructed under-designed according to seismic design provisions or load demands. Ductility of high strength concrete (HSC), compressive strength and service life of concrete structures which affected by the environmental degradation, corrosion of steel and upgrading of structures to current seismic code requirements can be performed by lateral confinement. Fiber reinforced polymer (FRP) composites have been used as longitudinal reinforcement, admixtures, and fiber wraps to improve flexure, shear, ductility and compressive strengths of reinforced concrete elements. FRP confinement can provide significantly higher confining pressure than the conventional methods and give it good potential in seismic design of existing and new structures. CFRP-confined circular reinforced concrete columns with high strength concrete will be designed and tested at Brno University of Technology; columns have diameter of 200 mm, height of 2900 mm, longitudinal reinforcement of diameter 8 mm, and transverse reinforcement of diameter 6 mm. The main objective of this experiment is to develop a design algorithm for CFRP-confined circular columns with high strength concrete.
