A few studies have examined the behavior of fibrous concrete columns reinforced with fiber-reinforced polymer (FRP) bars under eccentric loads. To examine the effects of various eccentrics and the addition of synthetic fibers to concrete on the eccentric compressive load behavior of the columns, three fibrous concrete columns reinforced with FRP bars were cast and tested under eccentric load in this study. The results showed that the specimens’ ultimate capacity under low eccentric loads was determined by the compression failure caused on by the crushing of the concrete. In addition, the flexural tension failure began in specimens evaluated under high eccentric loads. Finally, adding fibers resulted in improving the eccentric behavior of fibrous concrete columns.

摘要

A few studies have examined the behavior of fibrous concrete columns reinforced with fiber-reinforced polymer (FRP) bars under eccentric loads. To examine the effects of various eccentrics and the addition of synthetic fibers to concrete on the eccentric compressive load behavior of the columns, three fibrous concrete columns reinforced with FRP bars were cast and tested under eccentric load in this study. The results showed that the specimens’ ultimate capacity under low eccentric loads was determined by the compression failure caused on by the crushing of the concrete. In addition, the flexural tension failure began in specimens evaluated under high eccentric loads. Finally, adding fibers resulted in improving the eccentric behavior of fibrous concrete columns.
