NON-LINEAR ANALYSIS OF BUILDING STRUCTURES IN SEISMIC AREAS ACCORDING TO THE EUROPEAN STANDARDS, CASE STUDY

For the design and construction of buildings in seismic areas the European Standard EN 1998-1:2004 offers two non-linear methods, namely: a non-linear pushover based static method and a nonlineardynamic method. This paper discusses those methods which differ from one another in respectto accuracy, simplicity and transparency. Non-linear static procedures were developed in the worldwith the aim of overcoming the insufficiency and limitations of linear methods, whilst at the sametime maintaining a relatively simple application. All procedures incorporate performance-basedconcepts paying more attention to damage control. Application of the presented procedures isillustrated by means of an example of an eight-story reinforced concrete frame building.
