- Abstract
- The prediction of structural resistance to earthquakes provides the focus of this report. Particular attention was paid to developing an upper bound or critical ground excitation for a structure of major importance, so that a high level of confidence in the prediction of structural resistance may be achieved. The term critical excitation is defined here as the one among a class of credible excitations at a given structural design variable in question. Both linear and nonlinear structures were considered. To verify its practicality, the method was applied to several nuclear reactor structures. The results show that the method is conservative but not overly so. The responses obtained from the critical excitation are in the range of 1.1 to 2 times those produced by recorded earthquakes of the same intensity. To further enhance the practical applications, response spectra for different soil conditions were also produced.
