Project Abstract
This project furthers the use of simulated ground motions by engineers by demonstrating their
use for two specific engineering applications, by “validating the validation gauntlets” that are
implemented on the SCEC Broadband Platform (BBP) through their use in the two engineering
applications, and by merging/simplifying the gauntlets based on the project results. In addition to
demonstrating agreement between validation gauntlet results and comparisons of building
responses to simulated and recorded ground motions, a workshop is planned to provide
descriptions of the simulation models and validation gauntlets in terms that resonate with the
intended engineering audience.
Intellectual Merit The simulation of earthquake ground motions allows for physics-based interpolation/extrapolation of the relative-ly limited amount of available earthquake rupture and ground motion data. Validation of such models, the focus of the SCEC Ground Motion Simulation Validation (GSMV) Technical Activity Group (TAG), is both a fundamen-tal challenge and a necessity for understanding the threat of earthquake ground motions.
Broader Impacts Through collaboration of earthquake scientists and engineers, the SCEC Ground Motion Simulation Validation (GMSV) Technical Activity Group (TAG) advances the use and understanding of simulated ground motions for engineering applications. Reciprocally, the GMSV TAG improves the science and products of ground motion sim-ulation.

The BBP simulations provide ground motions for the sparsely observed large magnitudes, close source-to-site distances, and hence high response spectra of engineering interest.
