Assignment 1: Structural Health Monitoring and Retrofit Plan for an Aging Bridge
Scenario:
You are part of a structural engineering team responsible for monitoring and retrofitting an aging steel bridge that has been in service for over 70 years. Originally designed for light vehicle traffic, the bridge is now facing increased load demands due to a surge in both heavy freight and commuter traffic. Additionally, the bridge is located in an area prone to environmental stressors like temperature fluctuations and corrosion from exposure salts water systems.
Your task is to develop a comprehensive structural health monitoring (SHM) system tailored to the bridge′s current condition and propose retrofitting strategies to extend its service life and ensure its safety under the new load conditions.
Assignment Tasks:
Bridge Condition Assessment:
Conduct a detailed assessment of the potential structural vulnerabilities of the old bridge, such as fatigue cracks, material degradation (corrosion, rust), and overloading.
Research past inspection reports and consider the impact of increasing traffic loads on structural integrity.
Design of SHM System:
Propose a structural health monitoring system to continuously assess the bridge′s condition. Specify the types of sensors (e.g., strain gauges, accelerometers, temperature sensors) that should be installed, their locations, and how data from these sensors will be processed.
Consider how the system can detect and monitor critical areas, including joints, supports, and the main load-bearing components.
Retrofit Plan:
Based on the vulnerabilities identified, propose retrofitting strategies that can improve the bridge’s load-bearing capacity and protect it from further degradation.
Consider techniques such as reinforcing steel elements, applying protective coatings, and improving load distribution across the structure.
Sustainability and Cost Consideration:
Discuss the sustainability of your proposed SHM and retrofitting plan. Evaluate the cost-effectiveness of your solution and consider the lifespan extension it provides for the bridge.
Report:
Write a 2500-word report detailing the current condition of the bridge, the SHM system design, the retrofitting strategies, and the sustainability analysis.
Include diagrams showing sensor placements, vulnerable areas of the bridge, and any proposed retrofitting designs.

Submission Requirements:
2500-word report in a Word Document or PDF format.
Diagrams showing sensor placement and retrofitting designs (separate image files).
Cost analysis table for the SHM system and retrofitting strategies.
References in IEEE format.
