The application of this method to a building enables the user to quantify the expected building damage for different seismic intensities. The second objective is the development of a procedure for the \"Performance Based Seismic Design\". This procedure enables the designer to link different building performance objectives with different hazard levels (earthquake design levels). The developed method for the vulnerability evaluation satisfies the requirements given in Eurocode 8. The evaluation time is about one hour for Level I and 6 hours for Level II. Thereby Level I and II can be used to perform large-area vulnerability evaluations. One of the evaluation results are the expected building damage values for different seismic intensities. In addition, the probability of failure (Damage > 60%) is determined for the investigated building. The evaluation procedure also reveals some important seismic weak points. Appropriate rehabilitation/strengthening measures can eliminate the identified weak points, which in turn improve the seismic performance and reduce the expected losses. The results give the economic impact from an earthquake on a community, municipality, company or an individual building owner. Thereby, the economic losses can be reduced to a minimum by appropriate risk mitigation or risk transfer measures (favourable loans for strengthening, Insurances, etc.). The expected annual loss and the technical insurance premiums can also be determined in conjunction with a probabilistic seismic hazard analysis PSHA. In addition, a procedure for vulnerability evaluation in Level III is introduced. The vulnerability evaluation in Level III is a rigorous probabilistic building analysis. The probabilistic seismic hazard analysis PSHA represents the latest achievement in seismological hazard assessment. By implementing the PSHA into the dynamic analysis procedure the resulting evaluation procedure became very efficient and relatively convenient. The developed method for the \"Performance Based Seismic Design\" (PBSD) also represents a probabilistic design for different performance levels (damage states). The building owner/manager can define several design objectives in the PBSD (e.g. the building should remain operational after a very rare earthquake corresponding to a return period of 2475 years, etc.). The design process is interactive. The probability of exceedance of each requirement (design objective) is quantified and the procedure delivers the required spectral values for the initial design. Using this initial design, the probabilities of exceedance of each performance level (damage state) are calculated for the building. This calculation is done also by the effective probabilistic analysis method introduced in Level III. At the end the existing probabilities of exceedance (failure) are compared with the allowed ones given by code or building owner. If the existing values are much higher than the allowed ones the building design has to be modified using the analysis results. The developed method is suitable for the design of important buildings, which have to satisfy higher performance objectives than the traditionally based \"Life Safety\" objective.
