Model-based-systems-engineering for bridges: representing modular precast bridges with SysML

Model-Based-Systems-Engineering (MBSE) and its corresponding modeling language, SysML, have been widely used in mechanical and systems engineering. While its underlying structure was designed with systems engineering in mind, buildings in the AEC domain can also be represented using the same principles of structure, behavior, requirements, and parametrics. Specifically, bridge constructions can benefit from representation through clearly defined constraints and specifications. This paper focuses on developing a concept to adapt system engineering principles to the modular precast bridge construction space, resulting in a preliminary method of representing bridges with the system modeling language. SysML diagrams representing the core functions of an exemplary bridge were created to showcase the viability of using MBSE and the necessary modifications to be appropriately adapted into the AEC domain.
