[docs]classStewartEtAl2016VH(bozorgnia_campbell_2016_vh.BozorgniaCampbell2016VH):""" Implements the SBSA15b GMPE by Stewart et al. (2016) vertical-to-horizontal ratio (V/H) for ground motions from the PEER NGA-West2 Project. This V/H model is combined from SBSA15 by Stewart et al. (2016) as the vertical model, and BSSA14 by Boore et al. (2014) as the horizontal model. Note that this is a more updated version than the GMPE described in the original PEER Report 2013/24.
