Abstract:According to the test of five brick masonry walls reinforced with CFRP under low
cyclic loads, the seismic behavior of brick masonry walls reinforced with CFRP is studied. The test results show that the performance of brick masonry walls reinforced with CFRP is improved, and the main factors in effect of strengthening include the area, location of CFRP and anchor conditions. The shear strength formula for brick masonry walls reinforced with CFRP is presented, and has a good agreement with the test results.
