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

Abstract

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.
