GNGTS 2018 S essione 2.2 399 The 2D MRF along the x axis is extracted from the 3D model (Fig. 1c) and time-history analyses are performed using the selected sets. To understand whether the structural response obtained with the simulated accelerograms is comparable with that obtained with natural accelerograms, the mean values of different Engineering Demand Parameters (EDPs) resulting Fig. 1 - (a) MCSI BD computed at bedrock for the site of Trieste, (b) 3D S-MRF under analysis, (c) 2D analysed FEM model, (d) a set of spectrum-compatible natural response spectra, (e) a set of spectrum-compatible physics-based synthetic response spectra.
