New Ground Motion Selection Procedures and Selected Motions for the PEER Transportation Research Program. “Ground-Motion Selection for PEER Transportation Research Program.” Proceedings, 7th International Conference on Urban Earthquake Engineering (7CUEE) & 5th International Conference on Earthquake Engineering (5ICEE), Tokyo, Japan, 9p.īaker, J. NGA numbers and scale factors are provided, but the user will have to utilize other tools to obtain the associated time series. Matlab scripts to perform conditional selection using the NGA West-2 database. Scripts are provided for both conditional and unconditional selection. Matlab scripts to perform selection using only the greedy optimization algorithm, as described in the appendix of the paper. These scripts were used to select the PEER ground motions described below. zip file is provided containing the required scripts, which rely on the metadata file above. The target means and covariances are obtained corresponding to a pre-defined target scenario earthquake. Matlab scripts to select unconditional (structure- and site-independent) ground motions. Matlab scripts to select single-component ground motions matching the mean and variance of a target single-component Conditional Mean Spectrum or unconditional spectrum. These scripts were used to select the ground motions described in the Earthquake Spectra paper above. Matlab scripts to select two-component ground motions matching the mean and variance of a target geometric mean Conditional Mean Spectrum. It contains all response spectra and metadata for the NGA ground motion database, and will be used in the search process of all of the following codes. This Matlab data file should be downloaded and placed in the working directory of any of the scripts provided below. This website serves to provide that documentation, allowing others to reproduce the results published in the manuscript. While the papers describe the method, complete documentation of the project is best achieved by providing the software used to perform the analysis. This manuscript describes an approach for selecting ground motions whose response spectra match a target response spectrum mean and variance. “A computationally efficient ground-motion selection algorithm for matching a target response spectrum mean and variance.” Earthquake Spectra, 27(3), 797-815. This web page provides documentation and supporting software for the following manuscript: The material below is provided purely for archival purposes. Archive: ground motion selection algorithm Note: this material has been superceded by comparable content at this link.
