nga_cena_gmmsiteamp: The subroutine of CENA site amplification function

In wltcwpf/GMPE: A pacakge of commonly used Ground Motion Prediction Equations (GMPE)

The subroutine of CENA site amplification function

Description

This is a subroutine of CENA GMM for site amplification

Usage

nga_cena_gmmsiteamp(
  thisT,
  Vs30,
  PGAr,
  flin_coeffs = sea_2020_cena_flin_coeffs,
  fnl_coeffs = hea_2020_cena_fnl_coeffs
)

Arguments

thisT	One single input period. -1 is for PGV, 0 is for PGA, and 0.01-10 for PSA at these oscillator period range.
Vs30	Shear wave velocity averaged over top 30 m (in m/s)
PGAr	The PGA on reference rock condition (Vs30 = 3000 m/s)
flin_coeffs	The coefficient for linear site amplification from Stewart et al 2020 CENA Flin coefficients. You can use the internal saved data object, sea_2020_cena_flin_coeffs
fnl_coeffs	The coefficient for nonlinear site amplification from Hashash et al 2020 CENA Fnl coefficients. You can use the internal saved data object, hea_2020_cena_fnl_coeffs
