Abstract: Strain hardening cementitious composites (SHCC) have demonstrated durability superior to that of conventional reinforced concrete due to their unique cracking behavior which influences transport, as well as corrosion propagation and damage development. In addition to more durable infrastructure, SHCCs can result in more sustainable infrastructure when accounting for life cycle performance. Focusing on numerical modeling of SHCC deterioration, this paper presents an approach to operationalize SHCC design and maintenance for improved sustainability. This framework consists of two types of models: (i) material degradation models and (ii) life cycle assessment models.
Numerical modeling of deterioration is used to estimate the time to each repair. These deterioration models are coupled with environmental impact models of a given repair, rehabilitation, or strengthening activity based on a process-based LCA of individual repair activities. All models are formulated stochastically so that the time to repair and total sustainability impact are described by a probability density function. Results facilitate decision-making by infrastructure stakeholders when designing to meet sustainability targets.
