Full-Scale Measurements and System Identification on Sutong Cable-Stayed Bridge during Typhoon Fung-Wong

Mode Identifiability of a Multi-Span Cable-Stayed Bridge Utilizing Stochastic Subspace Identification

This study investigates the mode identifiability of a multi-span cable-stayed bridge in terms of a benchmark study utilizing stabilization diagrams of system model identified by means of the stochastic subspace identification (SSI). The cumulative contribution ratios (CCR) estimated from singular values of system model was also considered. Observations demonstrated that wind speed might influen...

Wind loads analysis at the anchorages of the Talavera de la Reina cable stayed bridge

Introduction Cable stayed bridges are a feasible choice for middle length spans and can be also an alternative to suspension bridges in the range of 1000 m spans. In the last three years, cable stayed bridges having more than 1 km span have been built in China (Sutong Bridge, 1088 m and Stonecutters Bridge, 1018 km). The increasing in length implies higher aeroelastic interaction with wind acti...

Data Interpretation and Continuous Modal Parameter Identification of Cable Stayed Bridge

For reliable identification of modal parameters, it is important to distinguish between abnormal data due to defects, malfunctioning, and anomalies in the sensors, from that of precise data. In case of long-term continuous monitoring data, it is imperative to identify any defects in the raw data very quickly and accurately to ensure that the identification is trustworthy. Exploratory Data Analy...

Investigation of Wagon Derailment Moving on Cable-Stayed Bridge Due to Rail Irregularities

Dynamic characteristics of the new curved cable-stayed bridge in Porto Marghera (Venice, Italy) from ambient vibration measurements

The paper summarizes the results of recent ambient vibration tests and operational modal analyses carried out on the new curved cable-stayed bridge erected in the Commercial Harbour of Porto Marghera (Venice, Italy). The ambient vibration tests were carried out as a part of the reception tests of the bridge before its opening and included the recordings of the system response in selected points...
