The O-SAM Project
O-SAM (Open Structural Analysis Models) is an open-source data model designed to facilitate access, updating, and storage of structural simulations within web-based platforms. It supports informed decision-making in construction and maintenance through a Digital Twin approach, and integrates seamlessly with various commercial software to foster collaboration and extend its usability.
Flexible and Reusable
Our O-SAM (Open Structural Analysis Models) data model is structured in JSON format, providing the flexibility to represent and extend structural analysis information seamlessly. This ensures the persistence of key data, such as material behavior and finite element characteristics, across projects and workflows. The open nature of O-SAM also promotes model reusability, as it remains independent of proprietary software and version constraints.
Open and Interoperable
The O-SAM structure and details are open-source, encouraging
broad adoption. A set of bi-directional converters to other structural analysis data models
and proprietary formats has also been developed. Currently, O-SAM supports bi-directional
conversions to IFC Structural Analysis models,
compatible with software such as SAP2000 and ETABS, as well as the Abaqus .INP finite
element format.
As this library of converters grows, O-SAM’s interoperability will expand, positioning it as
a central hub for structural
simulations and Digital Twins, facilitating visualization, storage and update.
Web-friendly Simulations
O-SAM is designed for the web. Its JSON structure allows
simulations to be represented and executed directly on online platforms. Finite Element
Analysis (FEA) routines can be seamlessly linked to O-SAM models, removing the need to
switch between applications or depend on proprietary software. These linked O-SAM-FEA
routines can also incorporate sensor data and advanced processing techniques, unlocking the
full potential of real-time, web-based structural simulations for informed
decision-making.
