Aerodynamic Effect of Non-uniform Wind Profiles for Long-Span Bridges
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole Andre (Chapter, 2019)Long-span bridges are often designed based on the assumption of wind field homogeneity. At the Hardanger Bridge, the wind field along the bridge span is monitored though 8 triaxial ultrasonic anemometers. Simultaneously ... -
Buffeting response of long-span bridges considering uncertain turbulence parameters using the environmental contour method
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole Andre (Peer reviewed; Journal article, 2020)Full-scale monitoring of the Hardanger Bridge has revealed significant turbulence-induced variability in the measured acceleration response. In this paper, a probabilistic model is used to describe the uncertain turbulence ... -
Efficient prediction of wind and wave induced long-term extreme load effects of floating suspension bridges using artificial neural networks and support vector machines
Xu, Yuwang; Fenerci, Aksel; Øiseth, Ole Andre; Moan, Torgeir (Journal article; Peer reviewed, 2020)Long-term extreme load effects are one of the primary concerns in the design of civil and offshore structures. Such load effects can be evaluated using the accurate but computationally demanding full long-term method or ... -
Evaluation of mast measurements and wind tunnel terrain models to describe spatially variable wind field characteristics for long-span bridge design
Lystad, Tor Martin; Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2018)The quality of the information about the wind field characteristics is crucial for accurately predicting the structural response of a long-span bridge subjected to dynamic wind loads. In this paper, in situ mast measurements ... -
Full-scale investigation of the effects of wind turbulence characteristics on dynamic behavior of long-span cablesupported bridges in complex terrain
Fenerci, Aksel (Doctoral theses at NTNU;2018:100, Doctoral thesis, 2018)The global demand for long-span cable-supported bridges are emerging. Impressive number of projects have been realized in the last two decades and many more projects are in their planning, design or construction phases ... -
Long-term monitoring of wind field characteristics and dynamic response of a long-span suspension bridge in complex terrain
Fenerci, Aksel; Øiseth, Ole; Rønnquist, Anders (Journal article; Peer reviewed, 2017)Long-term monitoring data of wind velocities and accelerations on the Hardanger Bridge are used to investigate the relationship between the wind-loading and response processes. The extensive measurement system consisting ... -
Measured Buffeting Response of a Long-Span Suspension Bridge Compared with Numerical Predictions Based on Design Wind Spectra
Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2017)Wind-induced vibrations of the Hardanger Bridge deck were studied with reference to turbulence characteristics at the bridge site to evaluate the performance of the state-of-the-art methods for buffeting response analysis. ... -
Non-Stationary Buffeting Response of Slender Suspension Bridges
Løvik, Åsmund Romstad (Master thesis, 2018)This thesis presents a generalized framework for predicting dynamic structural response of slender, horizontal and line like structures. This general framework is subsequently adopted and streamlined to the Hardanger Bridge ... -
Numerical studies on the dynamic behavior of a superlong curved pontoon bridge under wind and wave actions
Fenerci, Aksel; Xu, Yuwang; Øiseth, Ole Andre (Chapter, 2019)Floating bridges serve as attractive solutions where classical bridge concepts are not possible. However, compared to more commonly encountered bridge concepts such as cablesupported bridges, their dynamic behavior remains ... -
Reliability Assessment of Long Span Suspension Bridges Subjected to Dead Loads
Antonsen, Kristin (Master thesis, 2016)In the present study the influence of standardized safety factors in large and heavy structures, where the major loading arises from self-weight of the structure itself, is considered. For this purpose, a reliability ... -
Site-specific data-driven probabilistic wind field modeling for the wind-induced response prediction of cable-supported bridges
Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2018)In this study, full-scale wind velocity measurements are conducted at eight locations on the Hardanger Bridge girder to investigate the possibility of a probabilistic representation of the turbulence field along the bridge ... -
Strong wind characteristics and dynamic response of a long-span suspension 1 bridge during a storm
Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2018)As Storm Tor struck the western coast of Norway, wind speeds and bridge deck accelerations along the Hardanger Bridge girder were recorded by the monitoring system installed on the bridge. Using 13.5 h of data, mean wind ... -
The Hardanger Bridge monitoring project: Long-term monitoring results and implications on bridge design
Fenerci, Aksel; Øiseth, Ole (Journal article; Peer reviewed, 2017)In design of slender suspension bridges, which are prone to wind excitation, accurate prediction of dynamic response is essential for reliable designs. However, dynamic response calculations involve many sources of ... -
Wind Field Variability in Complex Terrain: Lessons from the Hardanger Bridge
Fenerci, Aksel; Øiseth, Ole Andre (Chapter; Peer reviewed, 2019)Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ... -
Wind-Induced Response of Long-Span Suspension Bridges Subjected to Span-Wise Non-Uniform Winds: A Case Study
Forbord, Erlend Munkeby; Hjellvik, Hallvard (Master thesis, 2017)The Hardanger Bridge has a main span of 1 310 meters which makes it the longest suspension bridge in Norway and among the top 15 longest in the world as of 2017. The bridge consists of only two traffic lanes and one ...
