Reliability of bridge structures under wind loading: Consideration of uncertainties of wind load parameters

Effect of uncertainties in wind speed and direction on the fatigue damage of long-span bridges

“…The probability of each stress amplitude was computed using Eq. (12). The number of cycles for each stress amplitude was then found out using Eq.…”

“…Detailed study of influence of these parameters (PSD, turbulence, aerodynamic derivatives, damping) are also available [10][11][12]. Based on the observations from the above literature and the experimental results from wind tunnel, sensitivity analysis [39] was carried out to understand the influence of uncertainties on the standard deviation of stress response.…”

“…It was pointed out by Holmes [9] that deterministic approaches are commonly used to evaluate the wind loads on structures. Uncertainties associated with properties of the structure, wind turbulence and power spectral density, in buffeting were studied in the past by Caracoglia [10][11][12]. Jakobsen and Tanaka [13] addressed the uncertainties involved in determining the response of long span bridges.…”

Statistical buffeting response of flexible bridges influenced by errors in aeroelastic loading estimation

“…Reliability analysis for flutter has been performed by many researchers (Cheng et al, 2005;Dragomirescu et al, 2003;Kwon, 2010;Mannini and Bartoli, 2007;Pourzeynali and Datta, 2002;Prenninger et al, 1990;Scanlan, 1999), but less attention to structural serviceability during buffeting was given. Flutter derivatives (FDs) are force coefficients per unit length, routinely measured in wind tunnel tests.…”

Probabilistic evaluation of the aerodynamic properties of a bridge deck

“…As bridge structures are concerned, some recent reliability assessments have been carried out for actual case studies after the pioneering works of Prenninger et al (1990) and OstenfeldRosenthal et al (1992). These studies focus on the effects of static forces (Cheng and Li, 2009), buffeting (Caracoglia, 2008) or flutter (Ge et al, 2000;Pourzeynali and Datta, 2002;Cheng et al, 2005).…”
