M. Godio et alii, Frattura ed Integrità Strutturale, 50 (2019) 194-208; DOI: 10.3221/IGF-ESIS.50.17 205 Figure 7 : Fragility curves based on log-normal distributions obtained from the incremental dynamic analyses (IDA) carried out on URM walls subjected to relative-amplitude support motions. For α=0, motions of same amplitude; for α=0.5, motions with relative amplitude equal to the original input motion; for α=1, motions with relative amplitude equal to two times the original input motion and with fixed bottom support. Real discrete distributions based on the set of 10 ground motions are in dotted line and fitted log-normal distributions are in dashed, dashed-dotted or solid lines. PGA values are in units of g.
