Mehmed Čaušević, Mladen Bulić This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-7861689/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract The aim of the analysis and comments presented in this paper is to shed light on some doubts regarding the application of the second generation of Eurocode EN 1998-1-1 in the segment for determining the seismic action on buildings. One of the most important parts of the EN1998-1-1 standard refers to the determination of seismic load for buildings using spectra. Here, these spectra of the second generation are presented and discussed, and how they should be defined in the National Annex by each EU member state, especially those in the Mediterranean, to meet the needs of extreme actions due to earthquakes. For comparison, the seismic action on buildings obtained by applying the European standards currently in force is taken. If the value of the new spectrum S β,475 for the period T=1s is determined in a probabilistic way, as presented in EN 1998-1-1, it would not correspond to the level of seismic load that we have applied thus far. This paper provides recommendations on how this problem can be avoided because the second-generation Eurocode 8 offers, in addition to the use of spectra, another way of determining the seismic load for buildings. Presentation in this paper is based on the fact that the intensity of the seismic load that we have obtained by applying the currently valid spectra of the first generation has been relatively well affected, which is reflected in a kind of verification of the behaviour of newer buildings in recent earthquakes in the EU.
