摘要：Restoration of historical structures is a durative and arduous work in many countries. This research determines the seismic behavior of historical masonry walls in Thailand retrofitted by glass fiber reinforced polymer (GFRP) through the experimental method. Five masonry wall specimens were built in the traditional method in Thailand and tested under horizontal cyclic loading without vertical axial load. One wall served as reference specimen without retrofitting. Three walls were retrofitted with GFRP in different modes before loading. One wall was repaired after predefined damage and retrofitted with GFRP before secondary loading. The failure mechanism, shear strength, ductility and energy dissipation of walls were studied in detail. The results show that the shear strength and energy dissipation capacity of the historical masonry walls were distinctly improved after GFRP strengthening. doi: 10.14456/WJST.2015.31
