Energy Dissipation of Concrete Columns Confined with GFRP Ties Under Reversed Cyclic Loading
Fiber Reinforced Polymer (FRP) found to be effective as an alternative reinforcement material for concrete structures in severe environmental conditions. Recent research with full FRP internal reinforcement has proven its effectiveness subjected to simulated seismic loading. However, limited research is available for the hybrid reinforced concrete columns. Where the longitudinal reinforcement is steel and transverse reinforcement is Glass FRP (GFRP). This paper accesses the results of an experimental study of the two full-scale rectangular columns subjected to quasi-static cyclic loading. The columns have 400 × 400 mm cross-sectional dimension with an effective height of 1650 mm. One of the columns is completely reinforced with GFRP reinforcement; and the other column is a hybrid reinforced column reinforced with longitudinal steel reinforcement and confined with GFRP lateral reinforcement. The test results are presented and discussed in terms of general behavior focusing on failure progression and strength of column. Dissipated energy for individual cycles and cumulative dissipative energy was computed based on the experimental lateral load–displacement hysteresis response. Longitudinal bar type significantly affects the dissipated energy and equivalent hysteresis damping ratio was observed.
