Reliability-Based Calibration Of Design Wind Load, Snow Load And Companion Load Factors Considering Climate Change Effect, Qian Tang
Electronic Thesis and Dissertation Repository
Wind load and snow load are two of the environmental loads that need to be considered for structural design. This study compared the statistical characteristics of the annual maximum thunderstorm and non-thunderstorm winds based on the updated wind speed dataset and carried out the extreme value analysis for wind load by treating the synoptic and thunderstorm winds separately. The results indicated that for southern Ontario and the southern part of the Prairies, the extreme winds could be dominated by thunderstorm winds. The consideration of both thunderstorm winds and synoptic winds separately to recommend the reference wind velocity pressure for the …

Calibration Of Fatigue Design Wind Pressure For Sign, Luminaire, And Traffic Signal Support, Guigui Zu
Electronic Thesis and Dissertation Repository
The study is focused on calibration of fatigue design wind pressure for sign, luminaire and traffic signal support under natural and truck-induced wind gusts. The design of the support structures in Canada is governed by the current Canadian Highway Bridge Design Code (CHBDC). However, the code is not specific on the fatigue design wind pressure (natural or truck-induced) for these structures. Although there are equivalent static natural and truck-induced wind pressures for fatigue design recommended in the provisions of the American Association of State Highway and Transportation Officials (AASHTO), none of relevant studies discussed the implied reliability by using these …
