Modeling and Control of Tensegrity-Membrane Systems
… systems is studied. A systematic method is developed to determine the equilibrium conditions of general tensegrity-membrane systems. Equilibrium conditions can be simplified when the systems are in symmetric configurations. For one-stage symmetric systems, analytical equilibrium …

Numerical modelling of ocular accommodation process
… of such a complex system requires advanced methods in both fields. There are at least two major processes that bring about changes in this system; the accommodation process and age-dependent deterioration of this system known as presbyopia. While the focus of this thesis is primarily on the …

Elastic and ultimate behaviour of skew composite slab-on-steel girder bridges.
… stages of loading. In this work, both the nonlinear finite element method and the yield-line theory were employed in the theoretical analyses. The finite element method was used to study the behaviour and response of skew composite bridges in the elastic and post-elastic ranges of loading. …

Three dimensional behavior of retaining wall systems
… of selected earth retaining walls utilizing the nonlinear finite element method (FEM). These 3-D features are not explicitly incorporated in conventional two-dimensional (2-D) procedures that are commonly used to design these retaining walls. The research objective was accomplished utilizing the …

Experimental and theoretical study of encased-plate composite structural walls
… testing.Numerical analysis based on the nonlinear finite element method was carried out within the study. After validation against experimental results, the analysis was applied for a wide range of conventionally-reinforced and encased-plate composite structural walls. Numerical analysis …

Soft computing based parameter identification in pavements and geomechanical systems
… and the solution with conventional mathematical methods is often challenging due to the ill-posed nature of the problem. In this dissertation, a hybrid algorithm was developed to seek robust and fast solutions to this inverse problem. The algorithm is based on soft computing techniques, mainly …

Failure Prediction of Spatial Wood Structures: Geometric and Material Nonlinear Finite Element Analysis
… modes, and predict the ultimate load. The finite element models of this study are based on the Crafts Pavilion dome (Triax) in Raleigh, North Carolina, and the Church of the Nazarene dome (Varax) in Corvallis, Oregon. Modeling considerations include 3-d beam finite elements, transverse …
