“…According to equations (24a), (24b), and ( 19), the values of P 31 , P 32 , P 33 , and P 34 can directly determine the equivalent stifness and damping coefcients, thereby infuencing the active control force. In addition, equation (15) shows that P 31 , P 32 , P 33 , and P 34 can be determined from the ratio of β to α. Tus, the ratio of β to α plays an essential role in the active control force. Obtaining an appropriate value of β/α is critical for achieving the expected control performance.…”

“…Te length and fexibility of stay cables increase continuously with the span of cable-stayed bridges, and with that comes the risk of large-amplitude parametric vibration [15]. It was found that if the inherent frequencies of the stay cable and bridge deck are close to a certain range, the largeamplitude parametric resonance of the cable would occur easily [16].…”

As the stay cables of cable-stayed bridges become longer, parametric resonance with a large amplitude is more easily triggered, which becomes a vibration hazard of super-long stay cables. An increasing number of practical applications of vibration mitigation on stay cables demonstrate that vibration control strategies can effectively facilitate hazard mitigation and improve cable-stayed bridge reliability and service life. This study proposes a semiactive control approach to reduce the parametric vibration of super-long stay cables in cable-stayed bridges installed with magnetorheological fluid damper (MRFD). First, using the cable’s gravity sag curve equation, an equation governing the combined stay cable-bridge deck-damper control system was established to consider the effect of the chordwise force of cable gravity. Subsequently, a targeted LQR-based optimal active control law is proposed to provide the target control force in the semiactive control. The parametric influences on the performance of the LQR-based optimal active control were analysed to provide insight into the proposed control strategy. Since the semiactive control could achieve almost the same control efficacy of the targeted optimal active control, a semiactive control strategy employing MRFD is proposed to mitigate the parametric vibration of a super-long stay cable. Based on the proposed semiactive control strategy, the system was attached with the MRFD of the longest cable, S36, in the designed prototype long cable-stayed bridge. The efficacy of the established semiactive control system was also analysed. The analysis results confirm that the proposed semiactive control strategy and designed semiactive control system can perform similar to the LQR-based optimal active control. The semiactive control system attached to the MRFD can mitigate the parametric vibration of super-long stay cables in cable-stayed bridge engineering practice.

The large amplitude parametric resonance of stay cables coupled with bridges is a prominent hazard for super-long-stay cables in cable-stayed bridges. To provide insight into the nonlinear behavior of the parametric vibration of stay cables and the influence of the active control system on the nonlinear behavior, the nonlinear dynamic characteristics, bifurcations, and chaotic motions were investigated in the case of 1:2:1 internal resonance, 1:1:1 primary resonance, and 2:1:2 main parametric resonance. The stay cable’s gravity sag curve equation, including the chordwise force of gravity, is used to establish the equation governing the combined stay cable-bridge deck active control system to consider the effect of the chordwise force of cable gravity. Multiple scales were used to obtain averaged equations. Based on the average equations and taking the longest cable S36 in the prototype super-long-span cable-stayed bridge as the study object, the frequency-response and frequency-phase characteristics were analyzed, and the influence of the stay cable parametric vibration adopting an active control system was studied. The classical fourth-order Runge-Kutta method analyzes nonlinear dynamic behaviors, such as bifurcations and chaotic motions. The numerical results obtained here indicate that, in the case of a 1:2:1 internal vibration, increasing the excitation amplitude may result in chaos in the system, and the active control system can effectively avoid the existence of chaos. The analytical results also demonstrate that the active control system effectively mitigates the nonlinear parametric vibration of a super-long-stay cable coupled with vibration in cable-stayed bridges.

“…The stay cables can accumulate energy and oscillate with substantial amplitudes. This oscillation rarely endangers the structural integrity of the works, but it is disturbing for users and can cause fatigue damage to the cable stays if it is not controlled [21].…”

With the development of modern long-span cable-stayed bridges, due to the parallel strand cable (PSC) being assembled on-site strand by strand, which has the advantages such as no need for large-scale equipment for cable-making, delivery, hoisting, traction, tensioning, and the corrosion protection of the cable is excellent, it is more and more favored by designers. As load-bearing components, the stay cables are known as the life cable of the cable-stayed bridge. Its reliability and durability are the key factors that determine the safety and the service life of the cable-stayed bridge. In accordance with the requirements specified in international recommendations, in-depth research has been carried out on cable fatigue, anti-corrosion, and vibration control to optimize OVM250 PSC system. All research results have been successfully applied to cable stayed bridge projects.
