Numerical and Experimental Assessment of Dynamic Effects of Road Traffic in a Cable-stayed Bridge
نویسندگان
چکیده
This paper describes the development, updating and validation of the numerical modelling of the bridge-vehicles system of a new cable-stayed bridge (Salgueiro Maia Bridge, in Portugal), presenting several comparisons between calculated and experimental results, associated to the modal analysis, static and dynamic tests of the bridge under controlled heavy roadway traffic.

Static and Dynamic Characteristics of a Long-Span Cable-Stayed Bridge with CFRP Cables
In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration, nonlinear parametric vibration and wind f...
متن کاملModeling of Cable-stayed Bridges for Analysis of Traffic Induced Vibrations
This paper presents a method for modeling and analysis of cablestayed bridges under the action of moving vehicles. Accurate and efficient finite elements are used for modeling the bridge structure. A beam element is adopted for modeling the girder and the pylons. Whereas, a two-node catenary cable element derived using exact analytical expressions for the elastic catenary, is adopted for modeli...
متن کاملDynamic 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...
متن کاملDynamic impact analysis of long span cable-stayed bridges under moving loads
The aim of this paper is to investigate the dynamic response of long span cable-stayed bridges subjected to moving loads. The analysis is based on a continuum model of the bridge, in which the stay spacing is assumed to be small in comparison with the whole bridge length. As a consequence, the interaction forces between the girder, towers and cable system are described by means of continuous di...
