Aerodynamic analysis of long-span bridge cross-sections using random vortex method Kaya, Halil; Uzol, Oğuz; Department of Aerospace Engineering (2012) In this thesis, two dimensional, incompressible, viscous flow past bluff bodies and a bridge section, in which strong vortex shedding and unsteady attribute of flow are generally found, is simulated by means of random vortex method. The algorithm and method are described in detail. The validation and applicability of the developed numerical implementation to general wind engineering problems is illustrated by solving a number of classical problems, such as flow past circular and square cylinders. An applica...
Calibration of the finite element model of a long span cantilever through truss bridge using artificial neural networks Yücel, Ömer Burak; Hasançebi, Oğuzhan; Department of Civil Engineering (2008) In recent years, Artificial Neural Networks (ANN) have become widely popular tools in various disciplines of engineering, including civil engineering. In this thesis, Multi-layer perceptron with back-propagation type of network is utilized in calibration of the finite element model of a long span cantilever through truss called Commodore Barry Bridge (CBB). The essence of calibration lies in the phenomena of comparing and correlating the structural response of an analytical model with experimental results a...
Multi-support seismic excitation of long span highway bridges Gökdemir, Tunç; Askan Gündoğan, Ayşegül; Caner, Alp; Department of Civil Engineering (2017) Seismic design and analysis are common practices in bridge engineering which require both knowledge and experience. Technical standards, such as CALTRANS (2010) and AASHTO (2007) provide guidance on the analysis with the methods ranging from Response Spectrum Analysis (RSA) to Time History Analysis (THA). These methods are usually sufficient for obtaining the seismic behavior of common structures and capture the dynamic behavior with decent accuracy. However, this may not be the case for structures which sp...
Experimental and numerical investigation of the wind effects on long span bridge decks Iman, Ashtiani Abdi; Uzol, Oğuz; Kurç, Özgür; Department of Aerospace Engineering (2011) Long span bridges are susceptible to wind. Hence it is important to study their wind-induced vibrations to avoid any probable structural failures. In this thesis, the results of an experimental and computational investigation of the aerodynamic characteristics of trapezoid bridge deck cross-sections with three different aspect ratios (10, 12 and 15) and four different side angles (75º, 60 º, 45 º and 30 º) are analyzed and presented. The flow around rigid fixed bridge deck models is investigated to obtain t...
Comparison of 2D and 3D models in application to long wave motion and its interaction with a vertical wall Çınar, Gizem Ezgi; Yalçıner, Ahmet Cevdet; Baykal, Cüneyt; Department of Civil Engineering (2018) Tsunami-structure interaction is an important issue in the design of coastal structures. Numerical modeling of the tsunami-structure interaction has a vital importance in this manner to understand the behavior of the long wave motion around structures in a more detailed way. In this study, physical model experiments on solitary wave-vertical wall interaction performed by Arikawa (2015) are numerically studied using two-dimensional depth-averaged non-linear shallow water equations model, NAMI DANCE and three...
