Seismic Strengthening of Masonry School Building with Steel Mesh Mortar Splint

Quasi-static test on a half-scale two-story masonry model was carried out to study the seismic strengthening performance and damage characteristic of existing masonry school buildings. The wall piers between openings were partially strengthened with steel mesh mortar splint where the steel mesh is reliably anchored using vertical reinforcements. The results show that strong pier-weak spandrel failure mechanism is guaranteed due to the formation of global failure mechanism. The failure characteristic, energy dissipation capacity and load bearing capacity of masonry structure are significantly improved.
