000020000 520__ $$2eng$$aConcrete-filled fiber reinforced polymer tube (CFFT) columns, the new type of bridge columns as alternatives to conventional reinforced concrete columns, have demonstrated superior advantages on mechanical behavior and easy construction during the past few decades. A lot of researchers have investigated the behavior of CFFT cylinders under monotonic compression load, however, limited studies has been done on its performance under cyclic compression load, which reflects its earthquake resistant capacity in seismic region. Especially, the cyclic behavior of CFFT cylinders after long-term weather conditioning still faces uncertainties. In this study, CFFT cylinders were immersed into seawater solution with two different elevated temperatures for up to 450 days. Sustained axial load were applied to the cylinders during conditioning in order to simulate the real-life situation. Cylinders were taken out from the seawater solution periodically to conduct cyclic compression tests. It is observed from the test results that though the conditioned CFFT cylinders dissipated less energy than the unconditioned ones during the early stage, they can sustain larger strain and consume more energy in the large-strain stage.
