- Ground-motion model is:
_{v}is in g, V_{REF }= 750m∕s, a_{1}= 1.299, a_{2}= 0.3329, a_{3}= 0.00317, a_{4}= -1.24624, a_{5}= 0.2129, a_{6}= 7.5192, a_{7}= 0.3196, a_{8}= -0.06736, a_{9}= 0.09853, a_{10}= -0.20467, ϕ_{v}= 0.5753 (intra-event), τ_{v}= 0.3311 (inter-event) and σ_{v}= 0.6638. - Corresponding vertical model of Akkar et al. (2014a,b) (see Section 2.376). Derive by combining the models for the horizontal component and vertical-to-horizontal ratio rather than direct regression on data.
- Validate model by computing inter- and intra-event residuals using the vertical data and the proposed
model. Find model is unbiased w.r.t. M
_{w}, r_{jb}and V_{s,30}.
