Determination of Seismic Load for Buildings using Different Response Spectra and Application on Different Methods of Analysis
The response spectra defined in the appropriate Euro standards from the first and second generation (EN 1998–1 and EN 1 January 1998), which determine the seismic load for common buildings, are critically presented first. To avoid a reduction in earthquake loading on structures using response spectra, only a few points of the response spectra in the second generation of EN 1 January 1998 are determined by applying the probabilistic concept of seismic hazard assessment. The comparison of current response spectra in EN 1998– 1 is made with the uniform hazard spectra (UHS). The comment and application of the second generation of EN 1 January 1998 is a novelty that is introduced in this paper. On the basis of response spectra presented here according to EN 1998–1 and EN 1 January 1998 and other spectra obtained from real and artificial records, comparative different methods of analysis on one regular simple eight- story reinforced concrete frame structure are illustrated to find out how the kind of spectra and used methods of analysis influence the story displacements and story drifts of one simple regular structure. So, at the same time, the reader will be informed not only about novelties in the second generation of EN 1 January 1998 as far as response spectra are concerned but also understand the implication of various response spectra on the methods of analysis of building structures.
