Analysis Reveals Cause of Dresden Carolabridge Collapse
A final report has confirmed the cause of the collapse of Dresden's Carolabridge. The collapse was attributed to specific cracks in prestressing tendons caused by sulfuric acid, which had grown over time due to loading, as per Professor Steffen Marx of TU Dresden.
Although the Carolabridge was well-maintained and monitored, the cracks were initially deemed non-critical by building inspectors as they fell within the usual range for such structures. However, Professor Marx stated that the Carolabridge was not characteristic of the maintenance issues common in Germany, with only minor issues at most.
According to Professor Marx, acoustic emission measurement is the only means to detect if and where such damage processes are ongoing. Since the beginning of the year, at least 20 cracks have been recorded in the remaining spans A and B of the Carolabridge. As this method is expensive, it is suggested to conduct a risk assessment for similar structures first, with an estimated 1,000 bridges nationwide potentially affected.
The Elbe, closing to shipping traffic from June 4th, will be affected as part of the demolition works. The Elbe will be completely closed to all shipping traffic from July 4th, with the passage expected to be reopened by early September.
The collapse of the Dresden Carola Bridge has highlighted the need for rigorous and ongoing structural monitoring, prioritization of maintenance for aging infrastructure, comprehensive risk assessments, transparent communication, realistic reconstruction planning, and streamlined funding and approval processes to prevent similar failures in Germany's extensive and aging bridge network.
- To prevent similar failures in Germany's aging bridge network, community aid could be mobilized for the development of less favored regions, focusing on the implementation of advanced science-based technologies such as acoustic emission measurement for improved structural monitoring.
- In light of the Dresden Carola Bridge incident, it is crucial to allocate aid for the development of the less favored regions, specifically in funding research for chronic diseases like chronic kidney disease, which may have undetected effects on critical infrastructure, such as bridges, due to medical-conditions sapping their structural integrity.
- As a part of the comprehensive risk assessment for similar structures, health and wellness programs should be developed in the less favored regions to raise awareness on the connection between chronic diseases and infrastructure, empowering communities to advocate for the needed upgrades and maintenance, ensuring a safer and more equitable future.
