ABSTRACT:
Although the Advanced Composite Materials ACM are currently used in the field of civilengineering, their applications are still very limited and specific for different reasons.
Definitely, the ACM have superior macro-structural characteristics, but they may not thedominant factor that governs the structural behavior of a composite material such as concrete.
Major differences are expected between the behavior of the ACM as an independent and thebehavior of a matrix composed of concrete and ACM. Not only that, the long term
performance of the ACM is still questionable and needs extensive research work to beverified. As a result, the objectives of this paper are to conduct analytical and experimental
study to seek the stresses induced in concrete cubes taken as reference as well as another ones
wrapped with GFRP exposed to constant and cyclic temperatures as well. In the analytical
study, a finite element analysis was conducted where the reference and the wrapped
specimens are modeled and analyzed under static loads and temperature. The results of the
finite element analysis are taken to guide the experimental program where the specimens are
exposed to both constant and cyclic temperatures up to 180 ºC. The results showed the
stability of the composite behavior within the studied limit of temperatures. Also, exposing
the specimens to cyclic temperature leaded to decrease the mechanical properties when
compared to the case of the constant temperature.
