An overview of a database of cyclic tests of masonry walls is firstly presented in this thesis.\ud
The objective of the analysis of the database was to estimate the relationship between the\ud
damage and displacements of the masonry walls. A discussion on the typical failure\ud
mechanisms of masonry walls and definition of damage states is then presented in the first\ud
part of the thesis which addresses also the issue of rehabilitaiton and strengthening of\ud
masonry walls by different techniques. The aim of the thesis was to estimate costs of\ud
rehabilitiation and strengthening of masonry walls. For this reason six From the base of cyclic\ud
tests were selected from the database and analyzed in more details. The cost of reparing the\ud
damage in masonry walls was estimated and compared to the costs of construction of new\ud
wall. The results have shown that the procedures and reparing costs depend on the damage\ud
and the type of masonry. The cost of repairing of damaged walls per unit area is greater than\ud
the cost of replacing the wall or the cost of new construction.Therefore it not likely that hollow\ud
brick masonry will be reapried in the case of extensive damage
