pySRA 0.5.0

Site Response Analysis with Python

pySRA

Site response analyses implemented in Python. This Python packages aims to implement many of the features found in Strata. These features include:

• Input motion characterization:

  • Time series

  • Random vibration theory

• Wave propagation or site amplification:

  • linear

  • equivalent-linear

  • equivalent-linear with frequency dependent properties

  • quarter wavelength

• Nonlinear curve models:

  • Darendeli (2001)

  • Menq (2004)

  • Kishida (2012)

• Site and soil property uncertainty:

  • Toro (1994) Vs correlation model

  • G/Gmax and D uncertainty:

    • Darendeli (2001)

    • EPRI SPID (2013)

Development of this software is on-going and any contributions are encouraged.

Installation

pysra is available via pip and can be installed with:

pip install pysra

If you are using conda and a create a pysra specific environmental make sure you install ipykernels and nb_conda_kernels so that the environment is discoverable by Jupyter with:

conda install ipykernel nb_conda_kernels
