The efficiency of strengthening of brick masonry walls for seismic loads by application of different types of composite-reinforced coating has been investigated. Failure mechanism was characterized by delamination of coating or strips, which pulled off the masonry and buckled as soon as compression of the damaged masonry took place at repeated lateral load reversals. Whereas improved lateral resistance has been observed in most cases, the displacement capcacity remaind the same.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 1743207Most important rules and recommendations given in the standard are explained. At the same time, some specifications, assumptions and rules, are critically discussed, and suggestions fro modifications and improvements rea given on the basisi of experimental investigation and observations on the site. An example of seismic resistance verification of typical masonry building is included.
F.23 Development of new system-wide, normative and programme solutions, and methods
COBISS.SI-ID: 1541991European standard for the assessment and retrofit of buildings has been recently passed which, as a member of the family of Eurocodes, provides recommendations for the assessment of seismic resistance of existing buildings and specifies the values of design parameters. On the basis of observations after the earthquakes and experimental/analytical research, some modifications regarding the determination of the design seismic loads and design seismic resistance of this particular type of buildings have been proposed.
B.04 Guest lecture
COBISS.SI-ID: 1669223Experience and knowledge obtained in the last three decades, regarding the seismic behaviour of historic buildings, are summarized. Although experimental evidence exist, the rare opportunity that the efficiency of the proposed retrofit measures has been verified by repeated earthquakes, indicated that relatively simple strengthening measures prevent excessive damage and collapse of such buildings, if adequately applied.

The seismic behavior of typical residential confined masonry buildings constructed with aerated autoclaved concrete (AAC) blocks has been investigated. On the basis of test results, the correlation between the damage and storey drift at characteristic limit states has been analyzed and the values of typical design parameters, such as displacement capacity and structural behaviour factor, have been evaluated.
