TLDR
In this paper, the potential ingress and combined effect of moisture and temperature on pre-fatigued glass fiber-reinforced polymers standard test specimens were analyzed in environmental conditions similar to that of tropical environments.Abstract:
The paper discusses the potential ingress and combined effect of moisture and temperature on pre-fatigued glass fibre-reinforced polymers standard test specimens. An experimental investigation was conducted to analyse the behaviour of glass fibre-reinforced polymers’ in environmental conditions similar to that of tropical environments. The standard pre-fatigued glass fibre-reinforced polymers specimens were subjected to varying hygrothermal conditions: three different temperatures, i.e. natural bath, 45 ℃ and 55 ℃ to study the degradation in strength and related properties. Several macro-structural and micro-structural tests were conducted to determine the damage. The effect of these conditions on characteristics such as diffusivity, weight gain, resin volume fraction, conductivity and deterioration of ultimate tensile strength was determined. The maximum reduction in strength is found to be approximately 39% for the specimen exposed to 55 ℃ water bath for 60 days. This study shall be helpful in estimatin...read more

Flexural Behavior and Design of RC Members Using FRP Reinforcement
TL;DR: In this paper, the authors argue that the working-stress method is better suited for FRP-reinforced concrete structures and that the predicted ultimate moment capacity represents a highly variable state only attainable at a high level of deformation and crack opening and that depends strictly on concrete ultimate strain.
