Reinforced Concrete

This paper introduces Rational-RC, an open-source Python package designed to model the life-cycle deterioration of reinforced concrete (RC) structures using a probabilistic, modular framework. It integrates key deterioration mechanisms—such as chloride ingress, carbonation, corrosion, and membrane degradation—within a unified reliability-based approach. The tool supports calibration with site-specific field data and produces actionable predictions that support condition-based maintenance and infrastructure management.

Rational-RC is a practical life cycle deterioration modelling framework. It utilizes the field survey data and provides probabilistic predictions of the RC structure deterioration through different stages of the service life cycle. It covers various deterioration mechanisms such as membrane deterioration, concrete carbonation and chloride penetration, corrosion and cracking.
