By Erol Kalkan. This study develops and evaluates the modal-pushover-based scaling (MPS) method for scaling ground motions for use in nonlinear response history analysis of buildings. Six building structures with fundamental periods ranging from 0.6 to 5.6 sec, representing low-, mid-, and high-rise building types in California, as well as two bridges, were utilized for testing the MPS procedure. The ASCE 7-05 procedure was also applied to buildings in order to compare its performance with the MPS procedure in predicting the median engineering demand parameters (EDPs) and reducing their dispersion. The comparison led to four conclusions: (1) the MPS procedure leads to scaled ground motions that yield more accurate estimates of median EDPs; (2) the MPS procedure is efficient, as the dispersion of responses due to ground motion is much smaller compared to the ASCE 7-05 scaling method; (3) the practical version of the MPS method uses attenuation relations for elastic spectral ordinates that are currently available; new attenuation relations for inelastic spectral deformation are not required; and (4) for first-mode dominated structures, scaling earthquake records to the target value of the inelastic deformation is sufficient in producing accurate estimates of median EDPs and in reducing the dispersion of EDPs due to individual ground motions. Selecting a subset of highest-ranked ground motions leads to a method that is more accurate and efficient for estimating seismic demands for taller buildings. Kalkan conducted this research under the supervision of Professor Anil Chopra at UC Berkeley. December 2009, 117 pages.
