pystrata.motion.RvtMotion¶

class pystrata.motion.RvtMotion(freqs, fourier_amps, duration=None, peak_calculator=None, calc_kwds=None)[source]¶

RVT motion based on user specified Fourier amplitude spectrum and duration.

__init__(freqs, fourier_amps, duration=None, peak_calculator=None, calc_kwds=None)[source]¶: Initialize the class.

Methods

`__init__`(freqs, fourier_amps[, duration, ...])	Initialize the class.
`calc_attenuation`(min_freq[, max_freq])	Compute the site attenuation (κ) based on a log-linear fit.
`calc_osc_accels`(osc_freqs[, osc_damping, ...])	Pseudo-acceleration spectral response of an oscillator.
`calc_peak`([transfer_func])	Compute the peak response.

Attributes

`angular_freqs`
`arias_intensity`	Arias intensity [m/s].
`cav`	Cumulative absolute velocity [m/s].
`duration`	Duration of the ground motion for RVT analysis.
`fourier_amps`	Acceleration Fourier amplitude values (g-sec).
`freqs`	Frequency values (Hz).
`pga`	Peak ground acceleration [g]
`pgv`	Peak ground velocity [cm/sec].
