StructuralCodes

StructuralCodes is a Python library that gathers models from concrete design codes. It includes concrete and reinforcing steel properties, constitutive laws, crack width, creep and shrinkage per Eurocode 2 (2004 and 2023 editions), shear and punching per Model Code 2010, and a section calculator that builds a section geometry with rebars and integrates stresses. Concrete engineers use it to build transparent, automated calculation sheets in Python or Jupyter. Limitation: there is no graphical interface, Python 3.10 or later is needed, and code coverage is still partial.
