Ground Motion Intensity Measures (GMIM) tools

This repository provides a suite of ground motion intensity measure tools. These tools include codes for computing the following ground motion intensity measures based on ground motion records:

Function	Abbreviation	Description
get_PGA_cy	PGA	Peak ground acceleration
get_PGV_cy	PGV	Peak ground velocity
get_Ia_cy	Ia	Arias intensity
get_Ia_times_cy	Ia_times	Times to get to a Ia percentage
get_CAV_cy	CAV	Cumulative absolute velocity
get_CAVn_cy	CAVn	CAV on accelerations after applying a cutoff
get_CAVgm_cy	CAVgm	CAV on accelerations after applying a cutoff
get_CAVstd_cy	CAVstd	Standardized CAV
get_CAVdp_cy	CAVdp	Damage-potential CAV

Example

A detailed example on Jupyter Notebooks is presented here.
