We use nonlinear site response simulations to calculate Fourier-basad site amplification factors for California. The amplification factors are designed to correct Broadband Platform simulated time-series on reference site conditions, thus integrating site response for engineering structural design applications. Our amplification factors are conditioned to two site-specific parameters: Vs30 (representing site stratigraphy) and z1000 (representing basin depth); and are derived using the Stochastic Sediment Model for the shallow crust, and the BBP for source and path realizations. We also compute response-spectra based site amplification factors using our simulated data and compare results to the NGA-West2 GMPEs site amplification terms. Our factors best compare with those of BSSA14.
