Fundamental Concepts of Performance Based Earthquake Engineering

In modern earthquake engineering, seismic performance properties are more important than the resistance properties of structures. Seismic performance of a structure is related to the expected damage level under an earthquake excitation, and how this damage relates to safety and use of the building. Accordingly, estimation of member deformations becomes more critical than the estimation of internal forces since the deformations in the post elastic regions of the structure are well correlated with damage in these regions. Fundamental issues of performance based seismic design in the next generation of seismic codes are evaluated in this paper. Their ranges of applicability, limitations and prediction accuracies are evaluated comparatively. Finally, difficulties in the practical implementation of these procedures and the required level of engineering knowledge are discussed. Basic examples are presented on the implementation of performance based design.
