Behavior of reinforced concrete-filled GFRP tubes under eccentric compression loading
Abstract This paper presents the results of experimental and theoretical study on the behavior of reinforced concrete-filled glass fiber reinforced polymer (GFRP) tubes (RCFFTs) under eccentric compression loading. A total of six RCFFT specimens were tested, the effects of the following parameters were examined: GFRP tube thickness (4.5 and 6.0 mm), longitudinal reinforcement, inserted I-shaped steel, and eccentricity (20 and 40 mm). The results of this investigation indicate that the ultimate load capacity and ductility of the RCFFT specimens are improved in terms of increasing the thickness of the GFRP tube under eccentric load. However, increasing the eccentricity significantly decreases the load capacity of RCFFT specimens. The internal steel bar could enhance the rigidity and loading capacity of RCFFT specimens. Furthermore, ultimate load capacity and ductility of the specimen are increased significantly by inserting shaped steel into concrete filled GFRP tube, Also, the simplified design equations are proposed to predict the ultimate load capacities of RCFFT specimens.
