concreteproperties 0.2.1

A python package to determine cross-section propreties of reinforced concrete sections

concreteproperties is a python package that can be used to calculate the section properties of arbitrary reinforced concrete sections. concreteproperties can calculate gross, cracked and ultimate properties. It can perform moment curvature analyses and generate moment interaction and biaxial bending diagrams. On top of this, concreteproperties can also generate pretty stress plots!

Here's an example of some of the non-linear output concreteproperties can generate:

Installation:

For more detailed installation instructions, refer to the documentation.

pip install concreteproperties
