Shear Performance of FRP-Retrofitted Masonry Wall with Structural Columns

Abstract:

To overcome the shortcoming of unreinforced masonry (URM) structure, structural columns are added in its construction to avoid the sudden collapse. This kind of structures still suffers different degrees of damage in the earthquake. This paper assesses the in-plane shear behavior of masonry walls with structural columns retrofitted with FRP (fiber reinforced polymer). The tests of two half-scaled masonry walls under cyclic loading have been carried out. One wall was served as reference specimen without any retrofitting scheme. Another specimen was tested to the pre-defined damage level and then strengthened with FRP sheets in mixed retrofitted configuration. The shear behavior of retrofitted specimen was discussed and compared with the reference in the aspect of lateral shear strength, maximum displacement and energy dissipation.
