The high seismic activity on the Peruvian coast carries a potential risk of tsunamis that could affect the Peruvian coast, causing damage to people and structures. According to studies carried out by CISMID and Fondecyt, approximately 83% of the houses in Metropolitan Lima and Callao are made of masonry, mainly due to its low economic cost. The present experimental study aims to study the behavior of confined masonry walls under the action of perpendicular loads to the wall produced by the impact of tsunami waves, which is a field of research where it is still necessary to delve deeper with experimental studies of the structures under equivalent tsunami loads. As part of the experimental study, 2 confined masonry walls were built, which were tested under the action of perpendicular loads applied by means of hydraulic jacks with a force control simulating the forces induced by a tsunami. ...
