Proposal of response spectra in the second generation of Eurocode EN 1998-1-1 for seismic areas and comparison with the existing standard EN 1998-1: 2004

Mehmed Čaušević, Mladen Bulić

Abstract

Fundamental changes of the existing standard EN 1998-1, with incorporation of latest research results, are proposed in the second generation of Eurocode EN 1998-1-1. A spectrum of earthquake loads, defined by several points established in a probabilistic manner, is presented and commented on. In addition, the new EN 1998-1-1: a) introduces 12 return periods for earthquakes (instead of the previous two periods), b) cancels previous elastic spectra Type 1 and Type 2, c) introduces a new moment magnitude Mw instead of the surface magnitude Ms, d) introduces four limit states instead of the previous two NCR and DLR, etc.

Keywords
Eurocode, seismic hazard, response spectrum, limit state, behaviour factor, nonlinear static method
