The proposed list of IMs include both spectral shape and durationrelated proxies, shown to be the optimal IMs in several probabilistic seismic demand models of different structural types, within the framework of Performance-Based Earthquake Engineering. Second, we propose two quantitative approaches for the engineering validation of ground motion simulations, namely statistical hypothesis testing and information theory measures. We then demonstrate the application of these parameters and validation approaches to ground motion simulations computed using a variety of methods, including the Graves and Pitarka hybrid broadband method, the deterministic Composite Source Model (CSM) method and the stochastic white noise (EXSIM) finite-fault model. These types of validation exercises can highlight the similarities and differences between simulated and recorded ground motions for a given simulation method. The similarities should provide confidence in using the simulation method for engineering applications, while the discrepancies, should help in improving the generation of synthetic records.
