Figure 5 : Fragility curves based on log-normal distributions obtained from the incremental dynamic analyses (IDA) carried out on URM walls subjected to phase-shifted support motions. For β=0, in-phase motions; for β=0.5, motions with phase shift of 45°; for β=1: motions with phase shift of 90°. 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.
