Abstract/Description

This research is aimed at investigating and analyzing the rain-windinduced cable vibration phenomena experienced in cables of cable-stayed bridges and also the countermeasures employed by engineers to mitigate the large-amplitude vibration problem reported by various researchers around the world. In order to investigate the problem of the water rivulet creation at the top of the cable surface, a single-degree-of-freedom (SDOF) analytical model was developed and analyzed. This thesis studies...
Show moreThis research is aimed at investigating and analyzing the rain-windinduced cable vibration phenomena experienced in cables of cable-stayed bridges and also the countermeasures employed by engineers to mitigate the large-amplitude vibration problem reported by various researchers around the world. In order to investigate the problem of the water rivulet creation at the top of the cable surface, a single-degree-of-freedom (SDOF) analytical model was developed and analyzed. This thesis studies the aerodynamic instability of cables in cable-stayed bridges by doing literature review of a typical in-situ test, developing a single degree-of-freedom (SDOF) analytical model, and an ANSYS finite element model. Furthermore, a linear viscous damper that acts as a countermeasure to the large amplitudes of vibration is reported and analyzed. The suppression characteristics and damper effectiveness of such countermeasure are summarized.

In my thesis, I argue three assertions: 1) that the 21 st Century antiheroine who has figured so prominently in literature and film is an evolution of the heroine archetype that combines both the action-oriented traditional male hero archetype and the tragically flawed, antagonistic anti-heroine archetype, 2) that the foundation for this newly modified pop culture antiheroine can be traced back to Margaret Mitchell's iconic character, Scarlett O'Hara, and finally 3) that this new modem...
Show moreIn my thesis, I argue three assertions: 1) that the 21 st Century antiheroine who has figured so prominently in literature and film is an evolution of the heroine archetype that combines both the action-oriented traditional male hero archetype and the tragically flawed, antagonistic anti-heroine archetype, 2) that the foundation for this newly modified pop culture antiheroine can be traced back to Margaret Mitchell's iconic character, Scarlett O'Hara, and finally 3) that this new modem heroine archetype, the antiheroine, has become an integral part of popular culture, both in literature and film as well as other popular media. As my primary texts I used Margaret Mitchell's Gone With the Wind, the David O. Selznick film ofthe same title, Joseph Campbell's The Hero with a Thousand Faces, as well as several other primary and secondary sources, including the published volume of Margaret Mitchell's Gone With the Wind related letters.
