CSA-S16-python 0.1.2

Steel design equations based on CSA S16.

CSA S16 Python

CSA_S16_python is a Python package for structural engineers working with CSA S16:24. It includes a comprehensive set of functions to calculate factored resistances member and connection checks — all in accordance with CSA S16:24.

This package is designed for use in Jupyter notebooks and web applications, with support for rendered equations via the handcalcs and IPython.display libraries.
