Seismic damage and fragility of RC buildings.
Апстракт
Seismic actions cannot be predicted in time, location or intensity. Serious earthquake actions can cause the occurrence of different levels of damage of the elements and the structure as a whole, which can even lead to their collapse. The methods for evaluation of seismic performance of structures are discussed in this paper and the focus of the paper is on reinforced concrete (RC) buildings. Building structures are designed and built according to different standards that were valid at the time of their construction. Those standards were, more or less, less demanding than the current European, American and other modern standards. Criteria for the determination of damage degree are discussed in the paper. Review and comparison of international Code provisions related to this topic are discussed as well. Fragility analysis of existing buildings with different structural systems is a rational approach, based on the application of probabilistic methods. They are applied in order to determi...ne and predict the structural performance and probable levels of damage. The classification of damage level and residual bearing capacity is essential after strong earthquake. This is necessary in order to decide the appropriate interventions, such as shoring and others. They are evaluated based on the condition of structures, considering: residual deformations, cracks, crush of concrete and so on. The methods of nonlinear analyses are used in order to determine the structural response and the results of the analysis are used for the fragility assessment. Post-earthquake assessment and analysis of seismic performance are analysed.
