RESEARCH ON ECCENTRIC COMPRESSION BEHAVIOUR OF CFRP-CONFINED CONCRETE FILLED STEEL TUBULAR COLUMNS

Abstract

Abstract: This paper presents the results of a recent study on the eccentric compression behaviour of carbon fiber reinforced polymer (CFRP) confined concrete filled steel tubular columns. A total of 6 specimens were prepared and tested in three pairs under different eccentricities. The length to diameter ratio of all specimens is 5. Thin steel tube with diameter to thickness ratio of 100 was adopted for all specimens. The load-strain curves, load-deflection curves were obtained from the tests. The Jiang and Teng (2012) eccentric compression column model for FRP confined reinforced concrete was modified to predict the columns of present study, the theoretical load-deflection curve of the specimens were calculated and compared with test results.

Key words: FRP confined concrete filled steel tube, eccentric compression test, mechanical property, column model, composites
