Abstract
This dataset collects 75 sets of 11 horizontal-component waveform couples; each set is compatible with the elastic response spectrum as defined in the Swiss normative SIA261 (2020) for each combination of seismic zone (zones 1a, 1b, 2, 3a, 3b) and soil class (soil class A, B, C, D, E). More in detail, each set comprises 11 pairs of horizontal-component waveforms, referring to the recording of one seismic event by the two horizontal components of the same station. Each set of waveforms is compatible, in a predefined period range, with the elastic response spectrum defined by SIA261 (2020) – for a 975 years return period – for each possible combination of SIA261 (2020) soil class and zone. The compatibility is ensured by respecting the selection criteria listed in the Eurocode 8 (2022) draft released during the research project. The three different period ranges over which the compatibility is enforced are the following: 0.02 – 1.0 s, 0.1 – 2.0 s, 0.25 – 4.0 s. These period ranges cover the buildings with resonance period between 0.10 – 0.66 s, between 0.50 – 1.33 s and between 1.25 – 2.66 s, respectively; in fact, according to Eurocode 8 (2022), the compatibility between the selected waveforms and the normative spectrum must be ensured in the range 0.2T0 – 1.5T0, where T0 is the resonance period of the investigated building. In this dataset we additionally provide the vertical component of the selected horizontal-component recordings, modified with the same scaling factor applied to the horizontal components.
