Incorporating multi-physics deterioration analysis in building information modeling for life-cycle management of durability performance

Extending the application of Building Information Modeling (BIM) tools into the operation and management phases of a building's life cycle is a significant advance in recent years. However, few studies have investigated or developed tools for the life-cycle management of durability performance of built structures leveraging BIM. This gap is partly due to (i) the lack of an accessible interface that connects BIM software with durability models of built structures, and (ii) no available durability models that are fundamental in nature and thus can integrate with other tools. To begin addressing this gap, this paper presents a framework that uses the Application Programming Interface (API) within BIM to integrate physics-based durability performance models, which extends the application of BIM into the post-construction phases by enabling more accurate predictions of life cycle performance. An application of the framework is presented for analysis and management of a reinforced concrete structure.
