A suite of ground motion intensity measure tools.
Project description
gmimtools: A suite of Ground Motion Intensity Measure (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_CAVstd_cy | CAVstd | Standardized CAV |
| get_CAVdp_cy | CAVdp | Damage-potential CAV |
Example
A detailed example on Jupyter Notebooks is presented here.
