| Abstract: |
Externally bonded FRP has been regarded as an effective strengthening technique, but its application in the retrofitting of damaged confined masonry buildings hasn't been studied. This paper conducted a research on a scaled three-story confined masonry structures before and after retrofitted with BFRP. The masonry model was initially tested to failure on a shaking table, from which its cracking development, acceleration responses and displacement were recorded. Strengthening process, including crack repairing, was then carried out on the pre-damaged model in situ. The strengthened model was retested on the shake table to evaluate the effectiveness of BFRP strengthening technique. The test results showed that the seismic performance of damaged masonry structure was significantly enhanced by BFRP strengthening technique. |
