Abstract
New theoretical models that account for spatial as well as temporal
variation of earthquake ground motion can be used to generate
space-averaged input ground motions for structures with large, rigid
foundations as well as correlated input motions for structures with
multi-supports. A specific format for ground motion characterization
suitable for seismic analysis of spatially extended structures is
suggested, and some empirical validation is provided based on
statistical analysis of records from the Taiwan seismic array.
