Non-linear analysis methods in performance-based earthquake engineering
(Master thesis, 2016)Over the last decades, increasing computational power is allowing engineers to do more advanced earthquake assessments on structures. The actual performance during seismic loading of buildings can be assessed using complicated ... -
Non-Stationary Buffeting Response of Slender Suspension Bridges
(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 ... -
Nonlinear Dynamic Response of Concrete Structure with Soil-Structure Interaction
(Master thesis, 2015)A common assumption for a structure that is subjected to an earthquake is that the structure is considered fixed at the base. In this thesis, analyses where the soil is deformed and the foundation may be moved and rotate ... -
Numerical modelling and analysis of the interactions between the left ventricle and the mitral valve
(Master thesis, 2018)In order to develop treatments for various heart diseases, a finite element model of the left ventricle and mitral valve apparatus could be of help. The goal of this thesis was to develop a finite element model of the left ... -
Numerical Modelling and Analysis of the Left Ventricle
(Master thesis, 2015)The development of a well functioning finite element model of the left ventricle is an important step to better understand the pumping function of the human heart. This may be of interest when developing effective treatments ... -
On Locking-free Methods for Isogeometric Large Deformation Analysis of Geometrically Exact 3D Timoshenko Beams
(Master thesis, 2015)In this thesis the geometrically exact 3D shear-flexible beam model is discretized with the Lagrangian and the NURBS basis functions, and has been used as a basis to develop a family of locking-free NURBS-based elements. ... -
Operational Modal Analysis of Large Bridges
(Master thesis, 2015)As a part of the new coastal highway E39 which is being planned and built along the west coast of Norway by the Norwegian Public Roads Administration, state of the art methods of structural dynamics needs to be developed ... -
Operational modal analysis of the Dolmsundet Bridge during construction
(Master thesis, 2015)This study investigates the dynamic behaviour of a cantilever bridge during construction. The investigations are carried out using operational modal analysis techniques. The Second-Order Blind Identification (SOBI) Method ... -
Power Pylons in Aluminium - Behaviour of Axial Statically Loaded Hollow Cylinders in Aluminium
(Master thesis, 2016)This thesis studies the behaviour of axial statically loaded circular hollow cylinders in aluminium and is written as a part of the project Design of power pylons in aluminium customized for automatic production . ... -
Quasi-static and dynamic behaviour of fillet welded connections
(Master thesis, 2016)Introduction Understanding the behaviour of the joints in a construction is crucial for structural engineers. In fact, the behaviour of steel joints exposed to static loading is well documented. Steel joints exposed to ... -
Reliability Analysis of Reinforced Concrete using Non-Linear Finite Element Analysis
(Master thesis, 2016)The purpose of the thesis is to investigate methods that may be used for assessing the reliability in large concrete structures in combination with non-linear nite element analyses (NLFEA). Reliability methods are applied ... -
Shear Capacity Assessment of an Existing Prestressed Concrete Bridge with Corrosion Damage
(Master thesis, 2017)The thesis contains shear capacity calculations of the structural beams in The Hulvågen Bridge, a concrete element bridge consisting of prefabricated and pre-tensioned beams with a continuous cast-in-place bridge deck. The ... -
Sliding Stability of Lightweight Concrete Dams - Development of Numerical Models
(Master thesis, 2013)Sliding failure of lightweight concrete dams occur if the horizontal forces subjected to the dam exceeds the shear capacity of one or more sliding planes in the dam?s structure or foundation. Thus, sliding is a result of ... -
Statistical Validation of Rigid Body Rocking Response Models Against Experimental and Numerical Data
(Master thesis, 2017)Slender, free-standing structures subjected to ground motions, may substantially decrease the seismic moment and shear at the base by uplifting and rocking motion. However, the rocking motion response is sensitive to all ... -
Structural Safety Assessment of Reinforced Concrete Structures with Nonlinear Finite Element Analyses and the Significance of the Modelling Uncertainty - Application to Structural Walls
(Master thesis, 2015)Nonlinear finite element analyses (NLFEA) allow for simulation of the expected real nonlinear structural behaviour of reinforced concrete structures. NLFEA in structural safety assessment does however introduce potentially ... -
Submerged floating tunnels subjected to internal blast loading
(Master thesis, 2015)Design of structures against blast loading is of great importance and has received a lot of attention in recent years. The Norwegian Public Road Administration (NPRA) are currently investigating the potential for eliminating ... -
Tension-loaded bolted connections in steel structures
(Master thesis, 2015)The purpose of this thesis is to study the behaviour of bolted steel connections subjected to tension. Quasi-static conditions have been considered. By performing laboratory tests on single bolts and simple T-stub connections ... -
Traffic induced vibrations of cable-supported bridges
(Master thesis, 2016)When considering cable-supported bridges, forces from wind and earthquakes often governs design. Heavy vehicles can also excite considerable vibrations on long and slender bridges, and may excite other frequencies in the ... -
Utvikling og programmering av beregningsprogram for kontaktledningsmaster langs jernbanen
