Abstract Fiber Reinforced Polymer (FRP) is commonly used in structural repair and strengthening due to its high tensile strength, non-corrosive lightweight. On the other side FRP relatively brittle compared steel. This study hybrid consisting of GFRP CFRP, by combining two type with different characteristic it be expected that more will fail first followed elastic one, therefore creating a sequ...

The use of aluminum alloys for external strengthening reinforced concrete (RC) beams has been capturing research interest. Exposure to harsh environmental conditions can severely impact the efficiency. This works aims investigate degradation in mechanical properties alloy AA 5083 plates when exposed temperatures ranging from 25 300 °C. Quasi-static Isothermal tensile experiments were conducted ...

Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...

• Self-anchored prestressed CFRP plates without the need for mechanical end anchorage. Significant improvement in bending stiffness, crack width, and load-carrying capacity. Nonlinear finite element analyses of flexural cracks crack-induced debonding plates. This paper presents an innovative method prestressing carbon fibre reinforced polymer (CFRP) used as externally bonded reinforcement stren...

This paper discusses the Finite Element analysis (FE) conducted to predict behavior of Glass Fiber Reinforced Concrete (GFRC) beams without shear reinforcement (stirrups) and strengthen them with proposed techniques increase their strength. for this study, A total eighteen (18) (120 * 300 2200 mm) specimens were modeled using Ansys™ mechanical. The main variables percentage discrete glass fiber...

An experimental study has been carried out to investigate the behaviour of co-bonded carbon fibre reinforced plastics joints with a novel design incorporating a through the thickness local reinforcement. Different specimens were manufactured to investigate static and fatigue behaviour, as well as delamination size after impact and damage tolerance characteristics. The mechanical performances of...
