Behaviour of Cfrp Confined Low Strength Concrete Columns Under Temperature Changes

Abstract

In this study, an experimental program was established to understand the behaviour of FRP-confined low strength cylindrical and square-section concrete columns under temperature changes. The experimental program was divided into four groups. First group of specimens were kept under room temperature and used as control specimens. In the second group, specimens were exposed to predetermined heating-cooling cycles in a specially designed environmental test chamber. Third group of specimens were placed in water, kept in the environmental test chamber, and subjected to the same heating-cooling cycles. In the last group, specimens were subjected to outdoor exposure in Ankara, Turkey. After the aging tests, specimens were tested under uniaxial compression to determine the change in their mechanical properties.
