Dynamic response of a multi-span suspension bridge with floating pylons
Mjaaland, Anders Lessø; Øvstebø, Audun Mathias (Master thesis, 2017)The Norwegian Public Roads Administration is currently investigating the possibility of crossing the 500 m deep and 5 km wide fjord, Bjørnafjorden, located in Norway. Several concepts have been developed on behalf of the ... -
Dynamic Response of Suspension Bridge with Floating Towers
Gong, Shun Wei (Master thesis, 2016)The Norwegian Public Road Administration has been investigating the possibilities ofcrossing the fjords on the west coast of Norway for the coastal highway E39 project.For the 5 km wide Bjørnafjorden ... -
Dynamic Response of Suspension Bridge with floating Towers
Halden, Sondre (Master thesis, 2016)The Norwegian Public Road Administration has been investigating the possibilities of crossing the fjords on the west coast of Norway for the coastal highway E39 project. For the 5 km wide Bjørnafjorden a floating three ... -
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 ... -
Experimental Study on the Drag Forces on a Twin-tube Submerged Floating Tunnel Segment Model in Current
Deng, Shi; Ren, Haojie; Xu, Yuwang; Fu, Shixiao; Moan, Torgeir; Gao, Zhen (Journal article; Peer reviewed, 2020)In this paper, the drag forces on a rigid segment of a twin-tube submerged floating tunnel (SFT) under various Re number and submergence are experimentally investigated with a simplified rigidly connected tandem twin-cylinder ... -
Long-term extreme response analysis of cable-supported bridges with floating pylons subjected to wind and wave loads
Xu, Yuwang (Doctoral theses at NTNU;2018:229, Doctoral thesis, 2018)A suspension bridge with floating pylons is a possible solution to cross a fjord with a large width and great depth. This new concept is a combination of a slender suspension bridge and tension-leg platforms supporting the ... -
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 ... -
Numerical Study on the Dynamic Response of a Submerged Floating Tunnel Under Current Loads Based on the Segment Model Towing Test Results
Deng, Shi; Li, Shuai; Xu, Yuwang; Moan, Torgeir; Fu, Shixiao; Gao, Zhen (Chapter, 2020)Submerged floating tunnels (SFTs) are considered as one of the relevant concepts to replace ferry connection in the Norwegian Public Road Administration's plan to upgrade the E39 coastal highway. Current load including ... -
Prediction of long-term extreme load effects due to wave and wind actions for cable-supported bridges with floating pylons
Xu, Yuwang; Øiseth, Ole; Moan, Torgeir; Næss, Arvid (Journal article; Peer reviewed, 2018)The characteristic values of the extreme environmental load effects should correspond to a specified annual probability of exceedance. These load effects can be calculated using short-term or long-term methods. The full ... -
Prediction of long-term extreme load effects due to wind for cable-supported bridges using time-domain simulations
Xu, Yuwang; Øiseth, Ole; Næss, Arvid; Moan, Torgeir (Journal article, 2017)Many long-span bridges that are slender and susceptible to wind-induced vibrations are currently under construction all over the world. As nonlinear structural behavior and nonlinear displacement-dependent wind loads become ... -
Time Domain Modelling of Frequency Dependent Wind and Wave Forces on a Three-Span Suspension Bridge With Two Floating Pylons Using State Space Models
Xu, Yuwang; Øiseth, Ole; Moan, Torgeir (Chapter, 2017)Floating suspension bridges, one of several new designs to make it possible to cross deep and wide fjords, consist of three spans and supported by two tension leg platforms and two fixed traditional concrete pylons. Geometric ... -
Time domain simulations of wind- and wave-induced load effects on a three-span suspension bridge with two floating pylons
Xu, Yuwang; Øiseth, Ole; Moan, Torgeir (Journal article, 2018)The construction of a three-span suspension bridge with two floating pylons is currently being considered for crossing the 5-km-wide and 550-m-deep Bjørnafjorden in Norway. The bridge design represents a novel concept that ...
