Structural engineers constantly seek to improve the safety and performance of pedestrian bridges. This is particularly important if bridges are exposed to dynamic forces such as foot traffic and environmental factors. In Dewesoft’s latest case study, researchers used Dewesoft’s Advanced Data Acquisition System to conduct a dynamic characterisation. This study monitored a two-span pedestrian bridge and assessed real-world responses under various conditions.
Using advanced data acquisition systems, the team performed modal analysis. This identified key structural parameters, including natural frequencies, mode shapes, and damping ratios. The study also involved operational modal analysis (OMA) techniques. This allowed engineers to evaluate the bridge’s behaviours under ambient conditions without requiring artificial excitation.
To collect accurate measurements, engineers utilised high-precision accelerometers and Dewesoft’s data acquisition software. These tools ensured real-time monitoring and analysis. The results provided valuable insights into how the bridge responds to pedestrian-induced vibrations, helping to determine its structural integrity and long-term reliability.
What Researchers found using Dewesoft’s Advanced Data Acquisition Systems
The findings emphasise the importance of continuous structural health monitoring (SHM) in modern engineering. By integrating data acquisition technology into routine inspections, engineers can detect early signs of deterioration and implement proactive maintenance strategies—ultimately improving safety and extending the lifespan of critical infrastructure.
This study showcases how Advanced Data Acquisition Systems enable engineers to analyse complex structures with precision and efficiency. For a deeper dive into the methodology and findings, read the full article on Dewesoft’s blog: Dynamic Characterization of a Two-Span Pedestrian Bridge.
