Abstract Details

2015, Master of Science, University of Toledo, Civil Engineering.
In January 2015, another major icing event occurred on the Veterans’ Glass City Skyway. This event required all northbound lanes to close for a duration of 8 hours due to ice shedding. The shedding event occurred in a manner that has never been observed in field experiments or in previous icing events on the bridge. In the January 2015 event, a thin ice layer shed released in small fragments rather than the typical large sheet shedding observed in the past. The January 2015 icing event is documented thoroughly for the first time in this thesis. A weather monitoring system that provides early warning and continuous weather monitoring is only as accurate and reliable as incoming data provided by the sensors implemented on the bridge. There is data pertaining to the stay sheath condition throughout winter weather events, such as icing, that is considered invaluable and is not captured by any commercial sensor. The variables pertaining to the condition of the stay sheath that need to be captured include the presence of water and thickness of ice accumulation on the sheath itself. The University of Toledo icing research team has designed and developed two sensors to capture this information. The design, development and results from both the laboratory and field setting are presented in this thesis. This thesis will also discuss shedding observations made from the 2014-2015 ice accumulation and shedding experiments performed at the Scott Park field station. Although these particular experiments were primarily done to expose the new revised design of the University of Toledo Presence and State sensor to freeze thaw cycles, there were valuable and insightful observations made pertaining to ice shedding on stainless steel sheaths.
