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.

Latest Version (0.1.2)

Updated to included clauses from Chapter 27 Seismic Design including:

• Clause 27.1.7: Probable Yield Stress
• Clause 27.2.2: Probable moment resistance of a beam
• Clause 27.2.3.3: Column factored flexural resistance
• Clause 27.2.3.3: Comparing the sum of the factored flexural resistance of the column and to the probable load acting on the column at the beam-to-column intersection.
• Clause 27.2.4.2 a) & Clause 27.2.4.2 b): Horizontal shear resistance of the column joint panel zone

Fixed the following functions:

• stiffener_check_comp_flange()
