Abstract

This paper presents the results of quasi-static and low-velocity projectile impact tests on unrein- forced masonry (URM) walls retrofitted with a cementitious-based material known as Engineered Cementi- tious Composite (ECC). A total of 18 masonry wall panels were tested to assess the extent to which ECC can enhance the impact/blast resistance of the strengthened masonry walls by subjecting these series of panels to three types of load patterns namely patch load, uniformly-distributed load and impact load. Test results re- ported in this paper demonstrate the efficiency of the ECC-strengthening system in improving the ductility of URM walls, increasing their ultimate load-carrying capacity, enhancing their resistance against multiple low- velocity impacts and preventing sudden and therefore catastrophic failure.
