earthquakepy

A python library for earthquake engineers and seismologists.

Installation

earthquakepy can be installed using pip. It’s an absolute breeze. Try it!

pip install earthquakepy

Thats it! This will install the earthquakepy and other required libraries. Wasn’t that easy?

Import and use

Probably you know how to import the library. Let me just remind you.

import earthquakepy as ep

Getting started

• Read a PEER NGA record from file

ts1 = ep.read_peer_nga_file(filename)

• Read a raw file containing timeseries data

ts2 = ep.read_raw_timeseries_file(filename)

• Build a SDOF system object to carry out some magic later!

s1 = ep.sdof(T=1.0, xi=0.05)

• Get response of above SDOF system subjected to base excitation ts2

s1.get_response(ts2)

• Build a MDOF system object

import numpy as np

M = np.random.rand(3, 3)
C = np.random.rand(3, 3)
K = np.random.rand(3, 3)

m1 = ep.mdof(M=M, C=C, K=K)

• Read OpenSees node output file

o1 = ep.read_ops_node_output(filename, 3, compNames=["x", "y", "z"])  # 3 : ncomps = number of components per node

• Read OpenSees element output file

o2 = ep.read_ops_element_output(filename, 3, compNames=["x", "y", "z"])  # 3 : ncomps = number of components per element

• Read OpenSees JSON model file

model = ep.read_ops_json_model(jsonFile)

Each object generated above has its own methods which are given in detail in the documentation. Please click on this link to view it.
