Sažetak
There is a large number of old sacral buildings in Croatia built by excellent craftsmen in past centuries. Some of these buildings still stand without major and visible shortcomings while others were seriously structurally damaged. A masonry structure is usually very complex. Seismic damages inflicted upon these buildings are not to be compared to typical seismic damages. The behaviour of a typical structural element – the dome, was examined. The stress analysis of brick masonry dome has been carried out. Dome diameter is 11, 00 meters. The effects of permanent and earthquake loading on stress condition of the structure have been analysed. In the analysis of this structure, two approaches were applied. First, according to elasticity theory analytical expressions, and other, with finite elements. In the second approach, a space structural model has been developed. In both approaches, the effects of permanent loading and permanent plus earthquake loading have been analysed. Results are presented through stresses and displacements. The critical cross sections have been determined by the comparison of the stress magnitude with the known strength of such structure. Safety values for the dome concerning compression and tensile stresses have been determined for the chosen loading cases.
