The response of masonry structures to impacts is a topic of significant importance due to its implications in structural integrity and safety. In this paper, the impulsive response of unreinforced brick masonry walls to impacts was investigated through a series of laboratory pendulum tests. Four double-wythe clay brick masonry wall strips were constructed between reinforced concrete slabs and subjected to moderate-velocity impacts. The tests included both point-load and line-load impacts, with a non-rigid support condition for the upper wall support to simulate realistic axial load applications. Measurements included: load cells monitoring the axial load applied to the top of the walls, capturing the arching generated upon impact; high-speed cameras used in conjunction with 3D DIC, to monitor strain rates and crack evolution on the wall surface; and 3D LiDAR scans, to support the documentation of post-test observed damage. The findings offered a comprehensive and detailed analysis of the structural response of brick masonry walls subjected to impacts. By focusing on specific response metrics, the study elucidated the various failure mechanisms generated by the impacts. Additionally, the energy transferred during the impacts was quantified, providing a direct measure of the energy absorption capacity of the walls and its correlation with the observed failures.
