Experimental Investigation and Analytical Modeling of Eccentrically Loaded Composite Short Columns Confined with Glass Fiber-Reinforced Polymer Tube
This paper presents the results of the experimental program and analytical modeling for performance evaluation of the eccentrically loaded composite short columns confined with Glass Fiber-Reinforced Polymer (GFRP) tube. This test matrix included six specimens, which were tested in the variable eccentricity. Research findings indicated that the strength of the concrete-filled GFRP tubular column was enhanced correspondingly; however, the strength gain caused by the GFRP tube decreased as the ratio of e/d0 was increased. A nonlinear analysis that accounts for the change in eccentricity caused by the lateral deformation was proposed to predict the columns’ strength. A comparison between analytical and experimental results of the present study demonstrated the accuracy and validity of the proposed analysis.
