- Развој и унапређење метода за анализу интеракције конструкције и тла на основу теоријских и експерименталних истраживања (MPNTR-TR 36028)
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.View More
