Table 7: Summary of results for anchors subjected to repeated loading. Anchors were installed in walls made with weak mortar. decrease in the tension resistance, combined with a more pronounced scatter of the experimental tension resistance values. * 4. Anchors subjected to repeated loading have exhibited a moderate reduction of their tension resistance (by 20% approximately), both for brick and mortar locations. * 5. A significant observation is that the reduction of the tension capacity due to various adverse parameters, the increase in the displacement at tension resistance, as well as the effect of the investigated parameters on the scatter of the experimental results are closely related to the failure mode that takes place. It was observed that there is a variety of possible failure modes. Their effect can be interpreted, after testing, but their occurrence cannot be reliably predicted. Indeed, in addition to some basic failure modes (such as anchor or brick pull-out), further failure modes are observed, involving a smaller or larger portion of the mortar joint or the adjacent brick. Those failures seem to depend on the local conditions and, thus, they cannot be predicted on the basis of average characteristics of the materials or based on the construction typology of the wall. Therefore, all those aspects should be accounted for, when design values of tension resistance are set, by providing adequate factors. Those factors should cover not only the variability of material properties, the presence of cracks in the substrate, and the type of loading. They should also allow for consideration of the inherent large scatter of the data.
