A simplified analytical method for predictions of ship deckhouse collision loads on steel bridge girders
Sha, Yanyan; Amdahl, Jørgen (Journal article; Peer reviewed, 2018)Bridges across busy navigation channels are under the threat of accidental ship collisions. Many research works have been conducted to investigate the structural responses during ship bow-bridge pier collisions. However, ... -
An efficient approach for ship collision design of reinforced concrete pontoon walls
Sha, Yanyan; Amdahl, Jørgen; Yang, Kun (Journal article; Peer reviewed, 2019)This paper presents an efficient method for collision design of prestressed concrete pontoon walls. High fidelity finite element models of a container ship bow and a prestressed concrete pontoon wall are first established. ... -
Analysis and Design Bjørnefjorden Floating Cable-Stayed Bridge subjected to Large Ship Collisions and Extreme Environmental Loads
Wang, Boya (Master thesis, 2017)The safe pontoon has the additional ring stiffeners and the thicker girders and ring stiffeners as well. The peak forces corresponding to the original pontoon and the proposed pontoon are 26MN and 42MN respectively. The ... -
Analysis and Design Bjørnefjorden Floating Cable-Stayed Bridge subjected to Large Ship Collisions and Extreme Environmental Loads
Aalberg, Aleksander (Master thesis, 2017)The purpose of this master thesis is to analyse one of the proposed bridge design for the Bjørnafjorden crossing, exposed to extreme environmental loads and large ship impacts. This is a floating cable-stayed bridge with ... -
Analysis and Design of Bjørnefjorden Floating Cable-Stayed Bridge subjected to Large Ship Collisions and Extreme Environmental Loads
Osvoll, Ida Fagerli (Master thesis, 2018)The objective of this master thesis is to study the global behaviour of the end-anchored floating bridge across the Bjørnafjord when it is subjected to high energy ship collision and extreme environmental loads. The ... -
Design of steel bridge girders against ship forecastle collisions
Sha, Yanyan; Amdahl, Jørgen; Liu, Kun (Journal article; Peer reviewed, 2019)A key aspect in the design of mega bridge structures across navigable waterways is to ensure bridge safety with respect to accidental ship collisions. Special attention has been paid to providing sufficient impact resistance ... -
Large inelastic deformation resistance of stiffened panels subjected to lateral loading
Yu, Zhaolong; Amdahl, Jørgen; Sha, Yanyan (Journal article, 2018)This paper presents a simplified formulation for the assessment of large deformation resistance of stiffened panels subjected to lateral loading. The method is based on rigid plastic material assumptions and the use of ... -
Local and global responses of a floating bridge under ship-girder collisions
Sha, Yanyan; Amdahl, Jørgen; Dørum, Cato (Journal article; Peer reviewed, 2018)The Norwegian Public Roads Administration is running a project “Ferry Free Coastal Route E39” to replace existing ferry crossings by bridges across eight fjords in western Norway. Since most of the fjords are wide and deep, ... -
Numerical and analytical studies of ship deckhouse impact with steel and RC bridge girders
Sha, Yanyan; Amdahl, Jørgen; Dørum, Cato (Peer reviewed; Journal article, 2021)Bridges crossing navigable waterways are under the threat of accidental collisions from passing ships. However, previous research focus was mainly placed on ship collision with bridge substructures while ship-bridge ... -
Numerical Investigation of the Collision Damage and Residual Strength of a Floating Bridge Girder
Sha, Yanyan; Amdahl, Jørgen; Dørum, Cato; Yu, Zhaolong (Chapter, 2018)For bridges across wide and deep waterways, fixed foundation structures are not possible to be built due to technical restrictions. Alternatively, pontoon supported floating bridges which do not require fixed foundations ... -
Numerical investigations of a prestressed pontoon wall subjected to ship collision loads
Sha, Yanyan; Amdahl, Jørgen (Journal article; Peer reviewed, 2019)The paper presents a numerical investigation of the ship collision response for a floating pontoon. High fidelity finite element models of a container ship bow and a prestressed concrete pontoon wall are established. The ... -
Numerical investigations of the dynamic response of a floating bridge under environmental loadings
Sha, Yanyan; Amdahl, Jørgen; Aalberg, Aleksander; Yu, Zhaolong (Journal article; Peer reviewed, 2018)Floating bridges across wide and deep fjords are subjected to the environmental wind and wave loadings. In this study, the dynamic response of floating bridges under such loadings is investigated. A floating bridge concept, ... -
Simulation of shipping container impact with bridge girders
Sha, Yanyan; Liu, Zhenhui; Amdahl, Jørgen; Dørum, Cato (Chapter, 2020)One of the challenges in bridge design is to ensure bridge girder integrity under accidental collision loads induced by the superstructures of drifting ships. Such accidents can happen either during earthquakes or tsunami ... -
Ultimate and residual strength assessments of intact and collision damaged columns of the Bjørnafjorden floating bridge
Yu, Zhaolong; Wang, Xintong; Moan, Torgeir; Amdahl, Jørgen; Sha, Yanyan (Chapter, 2023)The Norwegian Public Road Administration (NPRA) has initiated an ambitious project to replace the current ferry crossing solutions with floating bridges over the wide and deep Norwegian fjords. This will substantially ...
