Data in Brief
|November 15, 2023
Summary
Structural health monitoring of the Vänersborg Bridge detected a critical crack in a truss member. This real-world damage data, captured before, during, and after the event, is valuable for developing infrastructure surveillance systems.
Area of Science:
- Structural Engineering
- Civil Engineering
- Infrastructure Monitoring
Background:
- The Vänersborg Bridge, a historic riveted steel bascule bridge (1914-1916), requires ongoing maintenance for railway and ship traffic.
- Previous assessments and maintenance have been conducted to ensure the bridge's operational status.
Purpose of the Study:
- To present a valuable dataset of sensor readings from a real-world bridge damage event.
- To facilitate the testing and evaluation of data-driven infrastructure surveillance techniques.
Main Methods:
- Installation of sensors to monitor load effects and behavioral changes.
- Continuous data recording at 200 Hz during 64 bridge opening events.
- Analysis of accelerations, strains, inclinations, and weather conditions.
Main Results:
- An abrupt change in bridge behavior was detected in March 2023.
- An emergency inspection revealed a significant crack in a truss member of the counter-weight.
- The dataset includes sensor data from before, during, and after the fracture event.
Conclusions:
- The provided dataset offers crucial evidence of damage in a practical scenario.
- This data is highly valuable for validating and improving data-driven methods for infrastructure surveillance and early damage detection.

The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it...

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
51
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

01:20Microcracking in Concrete
124
Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...
