Concrete-filled fiber reinforced polymer tubes (CFFT), have been mainly studied under static loading, and very limited research data is available for CFFT columns under cyclic loading. These studies showed the higher structural performance and the relevant use of CFFT for seismic design of reinforced concrete (RC) structures. Indeed, it is well known that CFFT can increase the ductility ratio which is a crucial factor in seismic design. Thus, research on cyclic behavior is essential to the development of new design guidelines using the technology of CFFT. This paper presents the results obtained from an experimental investigation to study the effects of the FRP tube thickness on the cyclic behavior of CFFT columns. Two full-scale CFFT RC columns are reinforced with FRP tube thickness of 4 mm and 8 mm. One control RC column designed according to the Canadian standards for bridges (CSA S6-06) is made for comparison purposes. The specimen setup consisted in a column-footing with the FRP tube embedded in the footing before casting of the concrete. The column is axially loaded under a constant load, while a horizontal hydraulic actuator applied a quasi-static lateral load on the head of the column. The tubes are made at the Composite Material Reinforcement Laboratory of the Sherbrooke University using the filament winding manufacturing process. Comparing the CFFT columns with the control column and also by taking into account for the difference in the concrete sections, we obtain for S0PS2V4 & V8 respectively, 44 % and 46 % more for first cracking moments; 26% and 4 1 % for yielding moments, and 2 1 % and 45% for the ultimate flexural moments. The ductility of CFFT columns are also better than typical RC column with the CFFT specimen reaching 11.38 % and 10.33 % compared to 8.47% for the control.
