DESIGN FOR SLENDERNESS IN CONCRETE COLUMNS INTERNALLY REINFORCED WITH FIBER-REINFORCED POLYMER BARS

In spite of their successful introduction into the construction market, widespread acceptance of fiber-reinforced polymer (FRP) reinforcement by the engineering community depends on timely development of design guidelines and specifications. Many properties can influence the slenderness of FRP reinforced concrete (RC) columns. In this paper, a rational method is developed for the analysis of slender FRP-RC columns. A detailed parametric study is also carried out. This study recommends reducing the current slenderness limit of 22 to 17 for FRP-RC columns bent in single curvature. It is also shown that the moment magnification method can be extended to FRP-RC columns. The current stiffness formulas, and the stiffness reduction factor, however, need to be adjusted either as sole functions of modular ratio or as functions of both modular ratio and eccentricity ratio.
