“…the corresponding periods are 16.3, 9.8, 5.3, 4.4, and 3.4 s) and the first mode is the longitudinal floating vibration. The dynamic characteristics are very close to those of previous results presented by other researchers (Xing et al, 2013). Compared to LRBS, SMA-LRBS (I and II) have lower periods because SMA wires increase the stiffness of isolation systems and as a result decrease their flexibility.…”

This article investigates the efficiency of a new generation smart isolation system, namely shape memory alloy wire-based lead rubber bearing, for the seismic response control of long-span cable-stayed bridge systems under near-fault ground motions. The constitutive model of shape memory alloy wire-based lead rubber bearings is coded and implemented into OpenSees as a new user element. This user element can accurately predict the re-centering capability and energy dissipation capacity of shape memory alloy wire-based lead rubber bearing under different excitations. The Sutong cable-stayed bridge in China, with a main span of 1088 m, is taken as an example. Results reveal that implementing shape memory alloy wires into lead rubber bearings can effectively increase the self-centering property and, as a result, reduce the residual deformation in shape memory alloy wire-based lead rubber bearings under near-fault ground motions. Shape memory alloy wires lead to an increase in the horizontal stiffness and energy dissipation capacity of shape memory alloy wire-based lead rubber bearings. The deck displacement is restricted effectively, and a superior structural performance is achieved in terms of the deck acceleration. Shape memory alloy wire-based lead rubber bearings can effectively reduce the base shear and base moment of the towers. However, it is observed that an increase in the shape memory alloy wire diameter may have negligible effect on the deck acceleration, tower base shear and moment, and in some cases, on the pier base shear and moment.

“…In the past, the main approach to control the seismically excited cable-stayed bridges was to support the bridge deck only by the cables, that is, the FS (Ali and Abdel-Ghaffar, 1995). Several as-built bridges are designed as FS, such as Yakohama Bay cable-stayed bridge (Japan) (Siringoringo et al, 2014), SCB (China) (Xing et al, 2013).…”

“…railings, maintenance rails, or crash barriers) at particular locations on the girder has also proven to be useful (Zhou et al, 2015). On the other hand, previous research has proved that tuned mass dampers (TMDs) are one of the most effective mechanical countermeasures for controlling the VIVs of long-span bridges and are therefore widely used (Morga and Marano, 2014; Xing et al, 2013). The phenomena and mechanisms of the VIVs of long-span bridges with symmetrical girders were primarily investigated in the aforementioned studies.…”

The buffeting of long-span cable-supported bridges under strong winds is one of the key issues in bridge wind engineering. In order to study the effectiveness of the multiple tuned mass dampers (MTMDs) in buffeting control of long-span bridges, the Sutong Cable-stayed Bridge (SCB) with a main span of 1088 m in China is taken as an example in this paper. The spatial finite element model of the SCB is established and the modal analysis is conducted based on ANSYS. After the 3D turbulence wind field of the SCB is simulated using the measured wind parameters, the time-domain buffeting analysis on the SCB is conducted with the aerodynamic self-excited forces included. According to the dynamic characteristics and the time-domain buffeting analysis results of the SCB, the parameter sensitivity analysis on buffeting vibration control with MTMD is conducted in ANSYS. The optimum parameters are then obtained with the construction difficulty and economic factors considered. Results show that the control efficiency is sensitive to the number of the TMD, mass ratio, frequency band-width ratio, and damping ratio. Both the vertical and the lateral vibrations can be effectively controlled when proper design parameters of a MTMD system are used. In addition, the control effect on lateral vibration is better than that on vertical vibration. Results obtained in this study can provide references for anti-wind design and buffeting control of long-span cable-stayed bridges.
