Abstract(s)

Detailed and entire research in the comparison of seismic behaviour of reinforced concrete structures under European seismic code and Azerbaijan seismic code are not yet provided. However, there are big interests from the Azerbaijan Republic to involve European codes as state construction norms in Azerbaijan. Because of this, comparison has been made to help Azerbaijan move to European Standards. The following aspects were taken into account in order to make a comparison of seismic codes: design states, structural types, ground conditions, important classes, seismic zones, horizontal elastic response spectrum, base shear force and distribution of the horizontal seismic forces. Chapter 4 compares results of the case study in Chapter 3. To make a seismic analysis, the existing constructed structure was taken into account to apply seismic codes of Europe and Azerbaijan. The Robot Structural Analysis software was used for modelling structure and analysing it behaviour and results. The several aspects of both seismic codes are quite similar, such as design limit states, seismic zones, but the most similar aspect observed in the research is that of the characteristics of ground types. The almost 80% of difference in base shear force is observed for studied building. Also, studies show that Azerbaijan code is much more conservative in terms of shape of elastic response spectrum in poor soil conditions than European seismic code. Basically, overall results of research show that Azerbaijan Construction Norms, in terms of seismic design, are much more conservative in all aspects comparing with European codes. The main reason for this is the high seismicity of number of regions of Azerbaijan. Also, to consider is the cost of construction materials in Azerbaijan is way less that the cost in Europe.
