Parametric Study on Fatigue Behaviour of Beam - Column Joint Retrofitted with Various Patterns of Fibre Reinforced Polymer Sheets

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 study. Fiber reinforced polymer composite material made up matrix fibres. It alternative method for retrofitting structures. In project work, RC beam- column model was developed externally wrapped using ABAQUS-CAE. Then parametric carried out beam-column retrofitted pattern like orientation, layers Various materials fibres carbon, glass basalt. Orientation were 00,- 450,450,900 CFRP&GFRP, CFRP&BFRP GFRP&BFRP Finally FEA analysis compared discussed respect Specimens are their performances corresponding un-retrofitted specimens under cyclic loading. been found that after CFRP, GFRP BFRP capacity had increases 44.56, 46.3 60.58% stiffness, ductility also increased.
