This paper presents experimental test on sliding collapse. An array of up to fifty three tests on dry masonry specimens has been performed. Each specimen is subjected only to self-weight and to a horizontal load, whose position is chosen from a predefined set of three different locations. For the rest of properties, all specimens are totally equal. For each of the three locations, two sub-arrays of ten specimens and one of thirty-three have been tested. For each specimen, pieces layout is randomly performed so that imperfections randomly spread throughout the specimen as well. The main aim of this work is the comparison of these static tests with the results obtained from several commonly used numerical methods, especially with the ones retrieved under the non-Standard Limit Analysis. This paper shows that when the contribution of mortar to the strength of the structure cannot be taken into account and collapse by sliding occurs, the solution for collapse load and mechanism can be multiple. Hence, and since the solution is not necessarily unique, we should carefully consider the limits under which all methods finding a unique solution can be used.
