Experimental Behavior of GFRP-Reinforced Concrete Squat Walls Subjected to Simulated Earthquake Load
This study addressed the feasibility of reinforced-concrete squat walls totally reinforced with glass fiber-reinforced polymer (GFRP) bars achieving the strength and drift requirements specified in various codes. Using noncorrodible GFRP bars represents an effective method for overcoming deterioration due to corrosion problems. The previous experimental studies on GFRP-reinforced midrise shear walls showed that GFRP reinforcement can control shear deformation, which is a major problem in steel-reinforced squat walls. Five full-scale concrete squat walls with an aspect ratio (height to length ratio) of 1.3, one reinforced with steel bars (as a reference specimen) and four totally reinforced with GFRP bars, were constructed and tested to failure under quasi-static reversed cyclic lateral loading. The reported test results clearly show that properly designed and detailed GFRP-reinforced concrete squat walls can reach high deformation levels with no strength degradation. The results also show that the achieved drift satisfies the limitation in most building codes. Acceptable levels of energy dissipation, compared to the steel-reinforced squat wall, were observed. The promising results can provide impetus for constructing concrete walls reinforced with GFRP and constitute a step toward using GFRP reinforcement in such lateral-resisting systems.
