Abstract Remote wind sensing can complement traditional anemometry at a bridge site and contribute to an improved wind-resistant design of long-span bridges. This study examines lidar measurement data recorded along 168-meter-long horizontal line perpendicular the main span suspension in complex terrain. The velocity records are obtained by pair continuous-wave Doppler lidars (short-range WindS...

An integrated life-cycle assessment and life-cycle cost analysis model was developed and applied to enhance the sustainability of concrete bridge infrastructure. The objective of this model is to compare alternative bridge deck designs from a sustainability perspective that accounts for total life-cycle costs including agency, user, and environmental costs. A conventional concrete bridge deck a...

Selected applications of fiber-reinforced polymer (FRP) sandwich structural elements in building and bridge construction are discussed. It is shown how in building construction this technology enables the integration of functions such as load-bearing capacity, thermal insulation, daylight entry and energy production, into single, large-scale and lightweight roof or façade panels. In bridge cons...

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...

Steel bridge has the advantages of large span capacity, fast installation speed, easy transportation, repair and replacement, been widely used in practical engineering. The deck pavement steel is a crucial link whole building cannot be ignored. For long bridge, generally phenomenon fatigue cracking, service life difficult to reach expected life. Laying multi-layered protective layer structure o...

The present study deals with the structural safety evaluation of a 50-year-old river bridge, called Baghetto Bridge, located in north Italy on Adda River. Generally speaking, hydraulic processes are main cause bridge failure. Scour and hydrodynamic loads have been largely studied by engineering community; however, practice, integration analysis is often missing. aim this research to provide mul...

Highway agencies monitor the condition of thousands bridge decks every year. Even though Ground Penetrating Radar (GPR) has been used in bridge-deck evaluation, Step-Frequency GPR (SF-GPR) provides advanced assessment yet requires extensive and complex post-processing analysis. An SF-GPR analysis system was recently developed for monitoring all state Maryland. The objective this study to develo...

To increase the maximum span of cable-stayed bridges, Uwe Starossek has developed a modified statical system. The basic idea of this new concept is the use of pairs of inclined pylon legs that spread out longitudinally from the foundation base or from the girder level. Spread-pylon cable-stayed bridge has distinct advantage like reduction of sag of cables and oscillation of cable during earthqu...

14 Deck inclination and vertical displacements are among the most important technical parameters to 15 evaluate the health status of a bridge and to verify its bearing capacity. Several methods, both 16 conventional and innovative, are used for structural rotations and displacement monitoring; no 17 one of these does allow, at the same time, precision, automation, static and dynamic monitoring ...
