Abstract:
Retrofitting materials like aluminum bars, steel laminates and glass fiber compounds has been used in the construction field for many decades. Carbon fiber compounds are the recent addition to the retrofitting materials. These studies are a comparison of flexural and shear strength of retrofitted beams with conventional beam. It also compares the experimental results with the analytical results. Analysis is done using the software ANSYS workbench. Carbon fiber fabric wraps are used for retrofitting test beams. Epoxy resin is used to bind the fabric to the beam in u â€“ shaped wraps which binds the flexural face and the web of the beam. Total number of 4 beams of size (1500 Ã— 200 Ã— 250) mm including conventional beam is used for the experimental tests (Two point loading). Difference in ultimate load, critical load, flexural strength and shear strength are observed in experimental tests, and are being compared with analytical results. The beams were wrapped with five layers of carbon fiber fabric strips of different widths, 300 mm, 250 mm and 200 mm respectively. The highest flexural strength was observed in the two point load testing of beam retrofitted with 300 mm wide strips (BU30).
