ANALYTICAL STUDY ON THE BEHAVIOUR OF BEAM COLUMN JOINT USING BASALT FIBER UNDER CYCLIC LOADING

The beam to column joints are considered as critic regions in reinforced concrete frames. Therefore the beam column joints must be ductile to resist the lateral load. An analytical investigation was carried out to study the effect of beam column joint. An analytical study is carried out by finite element model using ANSYS. The beam column joint specimens are tested under reverse cyclic loading applied at beam end. The specimens were designed in accordance to t Standard Specification IS 456 (2000). In ANSYS Solid 65 element is used to model the concrete and Beam 188 element is used to model the reinforcement. The basalt fiber is varied at 1.5% volume fraction of the concrete in the specimens. The result beam column joint specimens strengthened with basalt fiber exhibit better structural performance.
