“…This consideration is widely agreed in bridge aerodynamics and it is supported by full scale measurements (e.g. Fenerci and Øiseth (2018); Bocciolone et al (1992); Hui et al (2009)). Modern full-scale experimental techniques (e.g.…”

The influence of the low frequency turbulence components on the buffeting response of long span bridges was studied through experimental tests performed on a full bridge aeroelastic model in the wind tunnel of the Politecnico di Milano, using an active turbulence generator producing a correlated deterministic harmonic turbulence. The experimental evidence underlined the nonlinear effect of the low frequency incoming turbulence on the dynamic resonant response of the structure at higher frequencies. Numerical simulations are used to explain the bridge behavior considering the variation of the aeroelastic properties of the bridge with the instantaneous angle of attack and reduced velocity. Even though wind tunnel experiment uses an oversimplified wind spectrum with an intentionally high correlation along the main span, it helps to understand the nonlinear interaction between the low frequency and the high frequency buffeting response on a full bridge.

“…For this purpose, the simulation of the VIV and MIE forces on a single‐box girder was based on the aerodynamic characteristics of the Humber Bridge built in the United Kingdom (e.g., Brownjohn et al, 1994), which was designed for a similar structure with a much shorter span (about 1400 m). In particular, the model of the 3,000‐m simulated structure does not correspond to the real Humber Bridge, which has completely different structural characteristics and span, and which did not exhibit in reality large VIV (Bocciolone et al, 1992; Diana et al, 1992; Brownjohn et al, 1994; Brownjohn et al, 1995), as later described in .…”

“…It must be noted, however, that this second example is not related to the actual Humber Bridge, for which experimental and full‐scale results are available (Bocciolone et al, 1992; Diana et al, 1992; Brownjohn et al, 1994; Brownjohn et al, 1995). The simulated structure is different, that is, a suspension bridge with central span two‐and‐a‐half times longer than that of the Humber Bridge (1440 m).…”

The susceptibility of modern bridges to vortex-shedding-induced vibration is a major concern for researchers and designers. The relevance of this phenomenon is associated with the onset of large-amplitude aeroelastic vibration at moderate wind-velocity regimes due to synchronization, that is, lock-in, of the vortexshedding frequencies with those corresponding to the natural modes of the structure. Recent observations, either recorded during the monitoring of full-scale bridges or during experimental tests of deck models in wind tunnels, confirm the importance of these aspects during the operational life of the structure. In this article, a computer model for the simulation of the aeroelastic loading associated with vortex shedding in lock-in regime is presented, for a direct application to dynamic analysis of long-span bridges. This approach is based on earlier work focused on the response of slender vertical cylindrical chimneys to vortex-shedding excitation, which is here extended to noncircular cross sections. The numerical model was employed in conjunction with a finite- *

“…Some of the time domain approaches (Caracoglia and Jones, 2003;Chen et al, 2000) translate the reduced velocity dependence of the aerodynamic transfer function in the time domain by means of convolution integrals, always considering the linear problem of the small deck oscillations around the static equilibrium position that is reached under mean wind conditions. Experimental evidences (Bocciolone et al, 1992) outlined that the linear approach hypothesis may be not correct under the operating wind condition in presence of large fluctuations of the angle of attack induced by turbulent wind velocity components. The non-linear effects induced by turbulence have also been outlined and studied by means of wind tunnel tests (Diana et al, 2004b).…”
