i_2014_subroutine: The subroutine of GMPE of Idriss 2014

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

The subroutine of GMPE of Idriss 2014

Description

This is a subroutine of Idriss 2014

Usage

i_2014_subroutine(M, ip, R_RUP, Vs30, Fault_Type)

Arguments

M	Moment magnitude, a numeric value
ip	The index of working period in the per-defined periods: (0.01, 0.02, 0.03, 0.05, 0.075, 0.1, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 7.5, 10, 0)
R_RUP	Closest distance (km) to the ruptured plane
Vs30	Shear wave velocity averaged over top 30 m (in m/s).
Fault_Type	The indicator of fault type: 0 for strike slip & other non-reverse faulting; 1 for reverse

Value

An array of four values: (1) median spectral acceleration prediction (in g); (2) logarithmic standard deviation of spectral acceleration prediction; (3) logarithmic standard deviation of within event residuals; and (4) logarithmic standard deviation of between event residuals at the period of ip.
