Structural testing of the Qingdao Cross-Sea bridge
Project name: Qingdao Cross-Sea Bridge Test
Brief introduction: As one of the longest and most significant sea-crossing bridges in China, the Qingdao Cross-Sea Bridge serves as a vital transportation link that requires the highest standards of structural reliability and safety. Prior to its official opening to the public, it was absolutely essential to carry out thorough and comprehensive testing. This rigorous evaluation aimed to confirm that the bridge could reliably withstand the dynamic loads, environmental forces such as wind and waves, and various operational stresses it would encounter on a daily basis throughout its service life.
In close collaboration with national inspection departments, Dynatronic actively participated in the comprehensive full-scale static and dynamic structural testing of the Qingdao Cross-Sea Bridge, ensuring rigorous evaluation of its overall performance and safety. The project encompassed a wide range of testing activities, including:
Dynamic response monitoring under live vehicle loads
Static load testing to evaluate structural displacement and strain
Sports car experiments simulating high-speed, high-load conditions
Modal testing to identify the bridge’s natural frequencies and mode shapes
Given the long duration of the testing program and the massive volume of sensor data collected across numerous points, a significant challenge involved managing and analyzing the dataset efficiently. Dynatronic's data acquisition systems and advanced post-processing tools played a critical role in efficiently transforming raw signals into clear and actionable insights.
Our advanced systems successfully enabled engineers to achieve greater efficiency and precision in their work, improving overall project outcomes:
Process large-scale multi-channel data with high accuracy
Visualize vibration modes and structural behavior over time
Validate finite element models with real-world results
Identify potential areas of concern before the bridge's opening
Thanks to the use of precise instrumentation and highly efficient data handling processes, the project was completed successfully—delivering a thorough and comprehensive safety assessment that ensured public confidence in the structure’s ongoing performance and reliability.
This bridge test project effectively demonstrates how Dynatronic's advanced technology supports critical infrastructure projects by consistently delivering reliable data and providing valuable structural insight under challenging, real-world conditions.
