BIM-Based Durability Analysis for RC Structures

Building Information Model (BIM) is used to share and exchange information between different applications for considerable processes of Architecture, Engineering and Construction (AEC) projects, and it is the key technology to manage information throughout the entire lifecycle of a building, solve the problem of information silo and improve the productivity of AEC project. This paper presents an extension of the BIM technology that allows integrating durability factors into designing process, appraising durability and predicting residual life of building structures. Furthermore, by integrating national durability code, achievements of durability researches and the IFC standard which is developed by International Alliance for Interoperability (IAI) with the standard number of ISO10303 to facilitate AEC information sharing and exchanging, a BIM-Based Durability Appraising Software System for Reinforcement Concrete Structure is developed. Then the system is verified by a case study to be capable of improving lifecycle management of AEC projects, upgrading durability level and optimizing the lifecycle cost structure of building projects.
