FIG. 1.2 The first generation of PBEE: To achieve a desired “System Performance” at a given
“Seismic Hazard.” (J.P. Moehle, A framework for performance-based earthquake engineering,
in: Proc. ATC-15-9 Workshop on the Improvement of Building Structural Design and Construction
Practices, Maui, HI, June, 2003.)

FIG. 1.3 The PBEE concept; the first versus the second generation.

probabilistic damage analysis rather than the current deterministic approach
that considers 100% probability of exceedance, when an EDP value exceeds
predefined damage measures. Fig. 1.3 depicts the basics of two mentioned
methodologies.
