Experimental and numerical evaluation of the out-of-plane bending behavior of masonry walls retrofitted by Steel Fiber Reinforced Mortar coating

The Out-of-Plane (OP) bending behavior of Un-Reinforced Masonry (URM) walls retrofitted by Steel Fiber Reinforced Mortar (SFRM) coating was investigated by performing in-situ experimental tests on two one-way vertically spanning walls. The latter were part of a full-scale two-story hollow block masonry building provided with seismic floor diaphragms and a 30 mm thick SFRM coating applied only on the external surface of the structure. One of the two test walls was tested under monotonic loading whereas the remaining one was subjected to reverse cyclic loading.
