Conceptual structural design of footbridges - A case study of asymmetrically suspended bridges using parametric modelling
Aas, Herman Enger; Eick, Kristian Mathias (Master thesis, 2017)A bridge was designed for the conference "Footbridge 2017" in Berlin, on a site between the districts of Kreuzberg and Fredrichsthain. During the design of this bridge a number of different bridge concepts were conceived, ... -
Conceptual Structural Design of High-Rise Buildings with Wind Alterations
Hverven, Elise (Master thesis, 2017)The aim of this thesis is to develop a conceptual structural design for a tall building located in Oslo, Norway. For a structural engineering student, it is vital to reflect on how the structural system can enhance the ... -
Digital Workflow in Conceptual Structural Design - Parametric Design of Connections for Timber Gridshell Structures
Rognes, Øyvind Sunnvoll; Faugstad, Helle Stam (Master thesis, 2018)The question for discussion is how digital workflow, based on a parametric model, can be used as a method of design to increase the efficiency of spatial structure design. The study focus on the development of connections ... -
Dynamic Analysis of Offshore Concrete Structures subjected to Earthquake
Amundsen, Morten (Master thesis, 2012)This thesis attempts to study the dynamic response of offshore concrete structures by sequentially introducing physical phenomena which are related to those types of analyses. This is done by modelling a simplified part ... -
Dynamic Behavior of a Full Scale Laboratory Model of a Catenary System by Measurements and Numerical Analysis
Haugland, Fredrik Hugo (Master thesis, 2015)The behavior of railway systems, in particular the overhead contact line (OCL), is considered in this thesis. The modelling of such systems with the use of the finite element method are important to carry out, both to ... -
Dynamic behavior of contact lines for railways with laboratorial model setup according to Norwegian conditions
Hallgrímsson, Arnar Kári (Master thesis, 2013)Some domestic flight routes in Norway rank among the busiest in Europe. Experience has shown that, in countries such as France and Germany, high velocity trains can be preferable to flying, given that the distance is not ... -
Dynamic Identification and Modelling of a Pantograph
Knutzen, Anders Nygaard; Sivertsen, John-Arne Berg (Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Dynamic Parameter Investigation of a Full Scale Laboratory Overhead Contact Line Section Model
