Under sponsorship of the Federal Emergency Management Agency, the Applied Technology Council is engaged in a multi-year effort to develop next-generation performance-based seismic design criteria. The criteria will be applicable to the design of new buildings or the retrofit of existing buildings. Constructed around a structural reliability framework, the criteria will permit the design of buildings to meet specific performance objectives expressed with regard to potential earthquake-related human casualties, repair costs and interruption of building occupancy and facility function. Recognizing the varied capabilities and needs of stakeholders in considering these losses, the criteria will permit expression of performance in either a probabilistic or scenario-based manner. The first phases of the project are focused on development of practical procedures for predicting building performance. This performance assessment procedure includes characterization of site seismicity through ground motion intensity hazard functions, development of structural response functions that relate probable amplitude of structural response as a function of ground motion intensity, damage functions that relate the probability of experiencing different damage states as a function of the response parameters, loss functions that relate the probability of experiencing casualty, economic and occupancy losses as a function of damage, and practical procedures to integrate these functions to express building performance in the form of projected losses. The project is being conducted in coordination with parallel efforts by the three U.S. national centers for earthquake engineering research in order to take advantage of significant research at these centers. In addition, the project is coordinating with parallel efforts in the blast and fire protection communities as well as those under way by the model building codes and standards development organizations.
