Fig. 3. Capacity surfaces, based on fragility medians (x M ), expressed in terms of dimensionless peak ground acceleration (PGA*) as a function of limit dimensionless rocking amplitude angle (|θ max /α| lim ) and semi-diagonal block dimension (R), considering strong ground motion (SGM).

Fig. 4. Capacity surfaces, based on fragility medians (x M ), expressed in terms of dimensionless peak ground acceleration (PGA*) as a function of limit dimensionless rocking amplitude angle (|θ max /α| lim ) and semi-diagonal block dimension (R), considering all floor motions (FM).
