Abstract

The chapter delves into the in-plane behavior of clay brick masonry wallets strengthened by a textile-reinforced mortar (TRM) system. It begins by highlighting the poor seismic performance of unreinforced masonry (URM) structures and the necessity for strengthening techniques. The study focuses on the use of TRM composites, which offer a pseudo-ductile response and are particularly suitable for seismic strengthening applications. The experimental program involves in-plane shear tests on control and strengthened specimens, with some surfaces sandblasted to enhance bonding. The results demonstrate that TRM jacketing significantly improves the wallets' shear behavior, with sandblasting further enhancing the bond and increasing shear strength and ductility. The chapter concludes with a comparison of the failure modes and performance of the strengthened wallets, emphasizing the effectiveness of TRM jacketing and surface treatments in improving the seismic performance of masonry structures.
