Abstract
The doctoral dissertation analyses revitalization process of the existing
residential buildings whose basic structural system comprises load-bearing
wall system, and which were constructed in the period prior to enacting the
regulations of construction in seismically active areas. The reasons for their
revitalization are protection and preservation of the housing stock in order to
improve the quality of housing. In order to correctly evaluate status of such
structures, here are listed types and causes of damage, with necessary
classifications and tabular presentations. The status assessment is performed
from a developed methodological framework, which contains all the phases
and activities in the process, with a defined goal and contents.
The methods of rehabilitation and reinforcement of the basic load bearing
wall structure, as the first phase of revitalization in which bearing capacity
and safety should be ensured, as well as the necessary calculus, were
provided in accordance with Eurocode 6 and Eurocode 8. For the analysis
were selected two characteristics types of masonry buildings within a mixeduse
(but mostly residential) block in Nis. Variations of the walls bearing
capacity and load to compression and shear, as well as the variation of
horizontal relative floor displacements and absolute displacements by height
of the building for the selected models of bearing structure strengthening was
monitored by implementing the software package FEDRA for design of
masonry structures in seismically active areas, based on the principles of
Eurocode 6 and Eurocode 8, in order to select the most appropriate solutions
