Damage Identification Strategies for the Preservation of an Existing PC-Bridge

Key Points

Damage identification strategies aim to enhance the preservation of the Nibelungen Bridge and ensure its functionality.
Initial structural health monitoring was implemented in May 2023 to assess damage mechanisms like corrosion and inadequate shear capacity.
Model-based and data-based approaches are proposed to address the long-term safety of this historic prestressed concrete bridge.
The findings highlight the importance of applying structural health monitoring in preserving aging infrastructure for future generations.

Abstract

This paper explores the application of Structural Health Monitoring (SHM) as a decision-making tool for the preservation of the Nibelungen Bridge in Worms (NBW), a prestressed concrete (PC) bridge completed in 1953. The NBW exhibits damage mechanisms that are characteristic of PC-structures of that era, including corrosion of tendons and inadequate shear load-bearing capacity. To address these issues, an initial SHM system was installed in May 2023. The present study proposes damage identification strategies aimed at preserving the NBW. By leveraging SHM data, the study explores both model-based and data-based approaches to ensure the long-term safety and functionality of this historic structure.
