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...
