Abstract

A variety of methods are used in the repair and strengthening of structures. Some of them use traditional materials, but in cases where they are insufficient, new materials are used. Some interventions may take the form of repairs to several elements, while others strengthen thestructure as a whole. CFRP reinforcement method is one of these reinforcement methods.The method of strengthening with CFRP has been used in many studies recently.Therefore, this study was conducted. In this study, as a result of the reinforcement madeby wrapping 2.5mm thick CFRP fabric into the 20m heightconcrete chimneystructure. The differences between modal parametersof the concrete chimneyand CFRP reinforced concrete chimney were compared.These modal parameters are period and mode shapes.The first 5 modes of the situation with and without CFRP were examined with finite element method.A difference of 4.58% -25.32% was observed in the periods of the first 5 modes.Reinforcement with CFRP has been observed to be positive for safety on the concrete chimneys.
