Probabilistic Performance-Based Earthquake Engineering
One of the main attributes distinguishing performance-based earthquake engineering from traditional earthquake engineering is the definition of quantifiable performance objectives.
Performance objectives are quantified usually based on life-cycle cost considerations, which encompass various parameters affecting structural performance, such as, structural, non-structural or contents damage, and human casualties.
Probabilistic performance-based engineering can be distinguished by defining probabilistic performance objectives.
•There is uncertainty in the future ground motion that is going to take place at the site of the engineering project.
•There is uncertainty in determining the parameters and building the mathematical model of the real structure.
