DEVELOPMENT OF A GROUND MOTION SCALING METHOD CONSIDERING MULTI-MODE EFFECTS
Non-linear dynamic time-history analyses conducted as part of a performance-based seismic design approach often require that the ground motion records are scaled to a specified level of seismic intensity. Recent research has demonstrated that certain ground motion scaling methods can introduce a large scatter in the estimated seismic demands. The resulting demand estimates may be biased, leading to designs with significant uncertainty and unknown margins of safety. This paper proposed a novel ground motion scaling method considering multi-mode effects for seismic evaluation of high-rise buildings. It is shown that the scaling method that work well in reducing the scatter in estimated peak seismic demands for a wide range of structural characteristics.
