Dinesh Kumar | Mr. Nitin Thakur "Strengthening of High Strength Concrete Beam Column Joints using FRP" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-6, October 2020, pp.104-108, URL: https://www.ijtsrd.com/papers/ijtsrd33307.pdf

The entire world built-up space is being made with concrete being the basic construction material. The advancement in the construction technique has raised the height of buildings as compared to the past. Although the design of structures follows the safety and serviceability rules according to the specialized codes formulated by different countries as per the geographical location, the greatest threat to all the frame buildings is the phenomenon of earthquake. The sudden vibration of the earth on which the structure is resting makes the Beam Column joints the vulnerable part. This experience of large deformations during the seismic excitation is not feasible because this join is the first element which overtakes cracks in such situations. Many research scholar have formulated one of the best solutions to this problem is the confinement of beam column joints. From literature review it is found that use of fiber reinforced plastic can strengthen the joints and are being effectively used for retrofitting due to ease of accessibility and placement. This experimental study is carried out to investigate the behavior and/or performance of RC interior beam column joints by using FRP. In total four specimens have been casted and rehabilitated with CFRP (Carbon Fiber Reinforced Polymer), the specimens were subjected to incremental cyclic loading applied by hydraulic jacks under constant axial or gravity load, deflection was recorded corresponded to load. The behavior of rehabilitated specimen is compared to the undamaged specimens. It has been observed that the wrapping with double layer over double layers of overlay of CFRP sheets exhibit the great and satisfactory results among the entire wrapping scheme applied to the specimens.
