Structural modification with additional degrees of freedom in large systems
Canbaloğlu, Güvenç; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2009)
In the design and development stages of mechanical structures, it is important to predict the dynamic characteristics of modified structures. Since time and cost are critical in design and development stage, structural modification methods predicting the dynamic responses of modified structures from those of the original structure and modification properties are very important, especially for large systems. In this thesis structural modification methods are investigated and an effective structural modificat...
Site-Specific Design Spectra for Vertical Ground Motion
Gülerce, Zeynep (SAGE Publications, 2011-11-01)
This paper contains ground-motion prediction equations (GMPEs) for the vertical-to-horizontal spectral acceleration (V/H) ratio, and the methods for constructing vertical design spectra that are consistent with the probabilistic seismic hazard assessment results for the horizontal ground motion component. The GMPEs for V/H ratio consistent with the horizontal GMPE of Abrahamson and Silva (2008) are derived using the Pacific Earthquake Engineering Research Center's Next Generation of Ground-Motion Attenuatio...
Ground motion scaling for the prediction of the seismic response of concrete gravity dams
Duygu, Mustafa Berk; Arıcı, Yalın; Department of Civil Engineering (2014)
Designing dams for seismic safety gains importance as the number of dams are increasing as a result of increasing need in water storage and hydropower. To define a structure’s seismic safety, scaling of accelerograms should be considered as one of the most crucial elements. Appropriate scaling of ground motion records is required to better estimate the linear and nonlinear structural response of a structure. Although, in literature, there exist numerous methods dealing with this issue, it is required to det...
Wall structure and surface chemistry of hydrothermal carbon nanofibres
Ye, HH; Naguib, N; Gogotsi, Y; Güvenç Yazıcıoğlu, Almıla; Megaridis, CM (2004-01-01)
A transmission electron microscopy examination of hydrothermally produced carbon nanofibres/nanotubes with outer diameter 50-200 nm suggests that the tube walls are inclined with respect to the tube axis. The apex angles are in the range 8degrees- 16degrees. The structure of these tubes and their growth mechanism can be described by a conical-scroll model. The conical-scroll structure enables functionalization of both inner and outer tube surfaces. The outer wall of these nanofibres is shown to be covered b...
Structural vibration control in wind turbines
Koçan, Çağrı; Özgen, Gökhan Osman; Department of Mechanical Engineering (2019)
Wind turbines are exposed to many different sources of loads which cause significant vibrations during their lifetime. Vibrations in the wind turbine system reduce efficiency and decrease the fatigue life. Although vibrations cannot be completely eliminated, they can be mitigated or converted to the other forms of energy by using various vibration control approaches which then increase the lifetime of the wind turbine system. Lowering the vibration response of the wind turbine provides stability under normal ...
