Effects of aerodynamic interferences between heaving and torsional vibration of bridge decks: the case of Tacoma Narrows Bridge

Mathematical Models for Suspension Bridges

“…All these phenomena may contribute to amplify the oscillations but, for several different reasons, none of them is unanimously recognized to be the origin of wide torsional oscillations. As an example, we quote several sentences from [190] about aerodynamic interferences between vertical and torsional oscillations at the TNB:…”

Wind-structure interaction simulations of ovalling vibrations in silo groups

“…Although it has been studied extensively, there is still a lot of controversy in the literature as to what was the precise mechanism causing the ultimate collapse of the bridge [160]. Even in a recent extended overview of Païdoussis et al [190], no decisive explanation could be given for the phenomenon.…”

“…Even in a recent extended overview of Païdoussis et al [190], no decisive explanation could be given for the phenomenon. It has however become clear that the observed vibrations cannot be simply explained by vortex-shedding [24], buffeting or galloping [160,190] separately and the excitation mechanism must have been much more complex.…”

Research status on aerodynamic interference effects of wind-resistant performance of pylon

“…Tsurumi Fairway Bridge was studied by P.P.Sarkar through sectional model wind tunnel testing, the flutter derivatives of single deck and the flutter derivatives of deck downstream when deck upstream was elastic suspension assayed respectively in different space of deck and in uniform flow and turbulent flow [23] . Rowan A Irwin, Stoyan Stoyanoff and J M Xie et al investigated aerodynamic interference effects of the twin-deck of the new Tacoma narrows bridge which began building in 2003 [24] . Hunan University Professor Chen Zhengqing's team is background with Qingdao Bay Big Bridge and GuangZhou Pingsheng Big Bridge to mainly investigate the aerodynamic interference effects of main cable and girder [25,26,27,28,29,30] .…”
