Experimental Study On Brick Walls Strengthened By CFRP

Masonry structure is an important kind of the structures widely used in current buildings. With the accumulation of their service time and the development of demands on structural safety under earthquake, more attentions should be paid to reinforcement on masonry structure.Fiber reinforced polymer (FRP) as a kind of composite material with many outstanding features is widely used in the field of airspace, mechanism and reinforcement of civil engineering. About ten years, fiber reinforced materials, especially carbon FKF, for their higner weight-strength ratio, better resistance against corrosion and fire, and other merits, have being developed and adapted rapidly in America, Japan, and Europe.The FRP composites' marketing in China is very large. Considerable parts of constructions and bridges being used in our country need to be strengthened and repaired for different reasons. The application of FRP composites used to strengthen concrete structures has more advantages than other available strengthening methods in general, so the new technology has considerable value of research and application.The mechanical characteristic of the brick wall strengthened by carbon fiber reinforced polymer (CFRP) has scarcely been studies at home. Based on the test of the brick walls strengthened by CFRP, this text studied the effect on the brick walls' seismic capacity, which was connected with the necessarily of a actual civil project bricked. The mechanical behavior and displacement-based capacity were analyzed. A simplified design formula was also presented.At last, some conclusions were drew on the experiment in this paper. And the author gave some distinctive advices for further researching and engineering on FRP-reinforcement of masonry wall in the future.
