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 ... إقراء المزيد

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 ... إقراء المزيد

Fatigue Analysis of FRP Strengthened RC Slabs Reinforced with Plain Bars Under Moving Load
In Japan, old RC bridge-deck slabs were economically designed by small thickness without considering the fatigue resistance. These slabs are subjected to a huge repetition of moving loads. Therefore, they are suffering from fatigue damage. This damage is more significantly observed than that of slabs reinforced with deformed bars. To extend their fatigue life, a suitable strengthening technique is required ... إقراء المزيد

Fatigue analysis of RC slabs with plain bars and FRP strengthening based on bridging stress degradation concept
The safety of construction in the long-term performance is the main goal of structural designers. An example is seen in reinforced concrete (RC) bridge deck slabs that have been subjected to a large number of load repetitions. Therefore, many numerical and experimental studies have been conducted to predict the fatigue life of these slabs. Most of these studies focused on ... إقراء المزيد

Numerical simulation of FRP strengthening for RC slabs reinforced with plain bars under moving load
There are many existing RC bridge slabs reinforced with plain bars, and they are suffering from a huge number of load repetitions due to heavy traffic. Therefore, a suitable strengthening technique is required to extend their fatigue life such as externally FRP sheets. To take full advantage of this strengthening technique, it is beneficial to use a numerical method to ... إقراء المزيد
