sStatics

sStatics is a Python package for the analysis of planar truss structures using the displacement method. sStatics can be used to calculate displacements, internal forces, and support reactions, and to visualise structural behavior under applied loads. The package supports second-order analysis and influence lines for advanced structural assessment.

Installation

Download and install the current version of sStatics:

python -m pip install git+https://github.com/i4s-htwk/sStatics.git

See Installation for more information.

Disclaimer

sStatics is an open-source engineering tool originally developed within a research project at HTWK Leipzig and is now maintained and further developed by the i4s institute. While care has been taken to implement the underlying structural mechanics and numerical methods correctly—including the displacement method, second-order effects, and influence line calculations — it remains the user’s responsibility to verify and assess all results independently. The authors and contributors do not assume liability for any incorrect use or interpretation of the software. Refer to the license for details regarding permitted use and limitations.
