ABSTRACT
Earthquake loads for engineering design are usually represented in the form of response spectra determined through probabilistic hazard assessment. In some cases acceleration time-histories are also required to represent the seismic loads. These can be generated or selected on the basis of the design spectrum but a more rigorous approach is to select or generate accelerograms corresponding to a particular earthquake scenario. The difficulty lies in defining the earthquake scenario (magnitude and distance) which is compatible with the probabilistic hazard assessment. In this paper it is shown that the use of multi-parameter hazard assessment provides a simple method to define the hazard-consistent magnitude-distance pair.
