“…The cables are engaged in longitudinal excitations U a and U b at both anchorages, as well as vertical excitation V b at the lower anchorage (Siringoringo et al, 2014;Wei et al, 2011). In this study, only this mode is considered; therefore, all excitation frequencies are the same and without phase differences, as described by Equation (8):…”

“…The value of large amplitude was determined according to Yokohama Bay Cable-Stayed Bridge (Siringoringo et al, 2014). As described in reference (Siringoringo et al, 2014), the girder experienced large relative longitudinal movement of about 8 cm. The main span of this bridge is 460 m, while the Dongting Lake Bridge is 330 m. Assuming the amplitude is in proportion to main span, the large amplitude was then calculated to be 5.7 cm, which corresponds to .000468 of nondimensional value.…”

“…Thus, the large amplitude was selected as .0005. According to reference (Siringoringo et al, 2014), the large amplitude is less than the maximum allowable longitudinal displacement. Thus, these amplitudes are admitted values and less than that of serviceability limit state.…”

“…Thus, the girder has longitudinal vibration (rigid body displacement) under ambiance excitations, as in bridges observed by Siringoringo and Fujino (2006 and Siringoringo, Fujino, and Namikawa (2014) and other floating or half-floating cable-stayed bridge systems (Aoki, Valipour, Samali, & Saleh, 2013;Calçada, Cunha, & Delgado, 2005;Wei, Wang, & Feng, 2011). However, completely releasing the girder from longitudinal constraint causes another serious problem: significantly large longitudinal motion of the girder (Domaneschi & Martinelli, 2014;Siringoringo & Fujino, 2007).…”

In order to ascertain the effects of longitudinal girder vibration on the non-linear cable responses in cable-stayed bridges, this study established a mechanical model of a cable which is subjected to three excitations at each anchorage. Non-linear governing equations were derived by Galerkin method and solved numerically. Three longitudinal girder vibration amplitudes were selected to illustrate their effect on cable non-linear response under primary and sub-harmonic resonance. The numerical results show that partially releasing the longitudinal constraint between the girder and pylons ensures that longitudinal girder vibration eases cable vibrations. This provides scientific basis for designing cable-stayed bridge as floating or half-floating system from a non-linear vibrations of view. Two basic and mutually orthogonal excitation mechanisms were identified under the sub-harmonic resonance: external excitation and parametric excitation. Effects of global excitation amplitude and cable inclined angle on response distribution under sub-harmonic resonance were found.

SUMMARYStructural health monitoring of large multispan flexible bridges is particularly important because of their important role in civil infrastructure and transportation systems. In this study, the response of the Yokohama Bay Bridge (YBB), a three‐span cable‐stayed bridge, to the 2011 Great East Japan Earthquake is used to perform multi‐input multi‐output system identification studies. The extensive multicomponent measurements are also used to develop and validate data‐driven nonlinear mathematical models that can predict the response of YBB to various earthquake records and can accurately estimate its damping characteristics when the system is driven into the nonlinear response range. A combination of least‐square (parametric) and neural network (nonparametric) approaches is used to develop the mathematical models, along with time‐marching techniques for dynamic response calculations. It is shown that the nonlinear mathematical models perform better than the equivalent linear models, both for response prediction and damping estimation. The importance of having an accurate approach for quantifying the damping due to the variety of nonlinear features in the YBB response is shown. This study demonstrates the significance of constructing robust mathematical models that can capture the correct physics of the underlying system and that can be used for computational purposes to augment experimental studies. Given the lack of suitable data sets for full‐scale structures under extreme loads, the availability of the long‐duration measurements from the 2011 Great East Japan Earthquake and its many strong aftershocks provides an excellent opportunity to perform the analyses presented in this study.

Cable-stayed bridges require a careful consideration of the lateral force exerted by the deck on the towers under strong earthquakes. This work explores the seismic response of cable-stayed bridges with yielding metallic dampers composed of triangular plates (TADAS) that connect the deck with the supports in the transverse direction. A design method based on an equivalent single-degree of freedom approximation is proposed. This is proved valid for conventional cable-stayed bridges with 200 and 400 m main spans, but not 600 m. The height of the plates is chosen to (1) achieve a yielding capacity that limits the maximum force transmitted from the deck to the towers, and to (2) control the hysteretic energy that the dampers dissipate by defining their design ductility. In order to select the optimal ductility and the damper configuration, a multi- objective response factor that accounts for the energy dissipation, peak damper displacement and low-cycle fatigue is introduced. The design method is applied to cable-stayed bridges with different spans and deck- support connections. The results show that the dissipation by plastic deformation in the dampers prevents significant damage in the towers of the short-to-medium span bridges under the extreme seismic actions . However, the transverse response of the towers in the bridge with 600 m span is less sensitive to the TADAS dampers
