Software Tool
The developed web-based software platform serves as a centralized management and analysis tool for bridge infrastructure within the context of a multi-hazard environment. Built using the Django web framework, the system integrates database-driven functionalities, file handling, signal processing, and visual analytics to support a broad range of engineering tasks, from data collection and inspection tracking to fragility assessment. The platform is structured into several interconnected modules, each addressing a specific aspect of bridge lifecycle management. These include:
- Bridge Inventory Module – for registering and maintaining detailed records of bridges.
- Inspection Management Module – for logging inspection events and storing associated documentation.
- Measurement Processing Module – for uploading and analyzing time-history data (e.g., acceleration or displacement).
- Fragility Curve Analysis Tool – for visualizing the probabilistic vulnerability of a bridge based on selected inputs.
Its architecture follows the classic MVC (Model-View-Controller) paradigm inherent to Django, promoting maintainability and scalability.
