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 ... -
Nonlinear Earthquake Analysis of Bridges in Time Domain
(Master thesis, 2011)Asynchronous seismic excitation has in previous studies been shown to significantly alter the response of long-span bridges. In order to further investigate this phenomenon, this master`s thesis studies the seismic behavior ... -
Nonlinear earthquake response of integral abutment bridges on vertical and batter piles: A practical approach
(Journal article; Peer reviewed, 2023)This paper presents a new finite element framework for seismic analysis of IABs (and other similar structures) on vertical and batter piles that takes into account nonlinear soil-structure interaction. A previously developed ... -
Nonlinear Isogeometric Analysis vs NFEA of Tubular Joints
(Master thesis, 2013)In 2005, Hughes et al. introduced the isogeometric analysis. One purpose was to eliminate the conversion between geometry model and analysis model in finite element analyses. NURBS (Non-Uniform Rational B-Splines) were ... -
Nonlinear modelling of aerodynamic self-excited forces: An experimental study
