This paper describes fractographic features observed in aerospace composites failed under tensile loads. Unidirectional Carbon Fibre Reinforced Plastic (UD CFRP) and Unidirectional Glass Fibre Reinforced Plastic (UD GFRP) composite specimens were fabricated and tested in tension. The morphology of fractured surfaces was studied at various locations to identify failure mechanism and characterist...

This paper presents the details of a research program that was conducted to evaluate the two-way bending behavior of 3-D glass fiber reinforced polymer (GFRP) sandwich panels. The panels consist of GFRP skins with a foam core and through-thickness fiber insertions. While the behavior of these panels under one-way bending is relatively well understood the behavior under two-way bending has not y...

This paper describes the behaviour of two full-scale models of a portion of highway bridge slab reinforced with fibre reinforced polymer (FRP) reinforcement. The first slab was reinforced totally with carbon FRP (CFRP), and the second slab was reinforced with hybrid glass FRP (GFRP) and steel reinforcement. The models were tested under static loading up to failure using a concentrated load acti...

Shear failure of B-C joints is recognized as the primary cause collapse various moment-resisting frame buildings during recent earthquakes. When joint subjected to huge forces severe ground shaking and its behaviour has a very much influencing on structure, sometimes it may Leeds entire structure. To study energy dissipation with different types combinations FRP sheets used retrofit BC in this ...

In this research, three models of beam-column joint have analyzed under reversed cyclic loading by finite element method using ANSYS software. The first model was designed with a steel-reinforced (longitudinal reinforcement and stirrups), the second performed (GFRP) -reinforced in longitudinal only third (CFRP) only. behaviour loading, their load-storey drift envelope relationship energy dissip...

This paper presents a method of analysis for the response of concrete beams reinforced with fibrereinforced-plastic (FRP) tension rods and aramid spirals. Three different kinds of longitudinal reinforcement are adopted; CFRP, AFRP and GFRP. Both under-reinforced and over-reinforced sections are described. It is found that the ratio of neutral axis depth and effective depth can be used as an ind...

Abstract Since the nineteenth century, reinforced concrete was evolved as a crucial material for construction. This popular composite is broadly used in different building typologies. However, decaying of steel rebar due to corrosion identified hindrance that can affect quality structures. In reference this, glass fiber-reinforced polymer (GFRP) bar essential because corrosion-resistant propert...

Plantation softwood timber poles are associated with low natural durability, and it is also not clear what the effects of high humidity environment on long-term performance composite action integrity such a system. This paper presents durability study for proposed using (GFRP) glass fiber-reinforced polymer as confinement system wooden sourced from plantation timber. Radiata pine 6 m length wer...

A theoretical study of Glass Fiber Reinforced Polymer (GFRP) beams subjected to biaxial bending moments is presented with a focus on the influence higher-order effects maximum normal stresses. It shown that type loading causes dramatic increase in stress for GFRP beam when induced torsional are included. The demonstrates traditional first-order theory can grossly underestimate beam. Based numer...
