Effect of web reinforcement on the seismic response of concrete squat walls reinforced with glass-FRP bars

Effect of web reinforcement on the seismic response of concrete squat walls reinforced with glass-FRP bars
Six full-scale concrete squat walls reinforced with glass-fiber-reinforced-polymer (GFRP) bars were tested to failure under quasi-static reversed cyclic loading. Each test specimen measured 200 mm thick, 1500 mm long, and 2000 mm high. The test parameters were the configuration of web reinforcement (horizontal and/or vertical) and the horizontal web reinforcement ratio. The test specimens experienced different mode of failures as ... Read more

Prediction of Flexural and Shear Strength of Concrete Squat Walls Reinforced with GFRP Bars

Prediction of Flexural and Shear Strength of Concrete Squat Walls Reinforced with GFRP Bars
This paper presents an original study aimed at predicting the ultimate flexural and shear strengths of glass fiber–reinforced polymer (GFRP) RC squat walls subjected to quasi-static reversed cyclic lateral loading. Predicting the strength of GFRP-reinforced squat walls is critical for their safe design and acceptance of GFRP bar as reinforcement in such lateral-resisting structural elements. The test results of squat ... Read more

“Behavior of GFRP-Reinforced Concrete Squat Walls under Simulated Earthquake Loading

“Behavior of GFRP-Reinforced Concrete Squat Walls under Simulated Earthquake Loading
Steel-reinforced squat walls are used as the main component for earthquake resistance in low-rise structures. Deterioration due to corrosion of steel reinforcement is one of the major challenges facing the construction industry. Furthermore, given the low aspect ratio of squat walls, their behavior is dominated by inelastic shear deformations activated by the yielding of flexural reinforcement. These deformations degrade strength ... Read more

Experimental Investigation of GFRP-Reinforced Squat Wall Subjected to Lateral Load

Experimental Investigation of GFRP-Reinforced Squat Wall Subjected to Lateral Load
: Steel-reinforced squat walls are used as the main component for earthquake resistance in low-rise structures. Given the low aspect ratio of squat walls, their behavior is dominating by inelastic shear deformations activated by the yielding of flexural reinforcement. These deformations degrade strength and stiffness with subsequent shear failure, preventing the wall from achieving its flexural capacity, which is a ... Read more

ASSESSMENT OF STRENGTH, STIFFNESS, AND DEFORMATION CAPACITY OF CONCRETE SQUAT WALLS REINFORCED WITH GFRP BARS

ASSESSMENT OF STRENGTH, STIFFNESS, AND DEFORMATION CAPACITY OF CONCRETE SQUAT WALLS REINFORCED WITH GFRP BARS
The present study addressed the feasibility of reinforced-concrete squat walls totally reinforced with GFRP bars to attain reasonable strength and drift requirements as specified in different codes. Nine large-scale squat walls with aspect ratio (height to length ratio) of 1.33— one reinforced with steel bars (as reference specimen) and eight totally reinforced with GFRP bars—were constructed and tested to failure ...
