Abstract
In order to investigate the effective seismic strengthening methods for un-reinforced brick masonry (URM) walls in developing countries, a total of twenty confined and unconfined two-dimensional (2D) and three-dimensional (3D) brick masonry wall specimens with different wall reinforcing details are designed, constructed and tested under constant vertical axial loads of 0.48MPa and 0.84MPa, and alternately repeated lateral forces. One of the main conclusions obtained is that the confined brick masonry walls with connecting bars along the vertical wall-to-wall connections between URM walls and cast-in-place confined reinforced columns as well as the horizontal wall reinforcement are very effective for improving the seismic structural behavior of URM walls against severe earthquakes.
