Strengthening of Preloaded RC Beams Using Hybrid Carbon Sheets
Reinforced concrete (RC) beams subject to service loads of 40 or 60% of steel yielding were strengthened using hybrid continuous carbon fiber sheets. The hybrid systems were made of high-strength and ...

Thepresent paper investigates the suitability and effectiveness of fiber-reinforced polymers(FRP) in strengthening and/or repairing unreinforced masonry infill walls inreinforced concrete frames which are subjected to in-plane seismic/cyclic loading.For this purpose, a detailed experimental program was conducted. Specimengeometry, test setup, instrumentation, and a loading procedure that simulatesearthquake loading are presented in a detailed fashion. Results ofexperimental observations are discussed in the form of load-displacement hystereticloops and envelopes; column profiles; strain diagrams, and wall sheardistortion. The test results, in general, indicate that the useof glass FRP (GFRP) sheets as strengthening materials provides adegree of enhancement to the infill wall, upgrades its deformationcapacity, and makes the wall work as one unit. Theseresults thus show great potential for externally bonded GFRP sheetsin upgrading and strengthening the infill walls under in-plane seismicloads.
