“…Several works were carried out to investigate the vibrational behavior of cables (Cheng and Dong, 2016; Kangas et al, 2012; Kim and Jeong, 2005; Papadopoulos et al, 2012). Kang et al (2012) and Dan et al (2014) studied the inclined cables, and fibre reinforced polymer cables are also investigated for the vibration characteristics (Mei et al, 2018; Yang et al, 2014; Zhang et al, 2011). The slackness, fatigue, and fracture problem in cables were investigated by Wu et al (2003), Pellegrino et al (2010), and Suh and Chang (2000), respectively.…”

Vertical or inclined cables which are placed in bridges as a hanger system affect the dynamic performance of bridges. Inclined hangers can be used instead of vertical hangers to improve the stability of the bridge aerodynamically. However, inclined hangers are susceptible to fatigue more than vertical ones. Considerable signs of distress or slackness might be shown by some inclined hangers because of their location on the bridge. In this study, a cable-stayed arch bridge with vertical and inclined hangers has been compared to investigate the effect of hangers on the dynamic performance of the bridge. To reduce the internal cable forces and the probability of fatigue or force fluctuation in hangers, additional horizontal cables are applied on inclined hangers that transfer the tensile load from overstressed hangers to adjacent ones with lower forces. By modification, the results demonstrate the higher stiffness and human comfort level for the bridge that improve the dynamic behavior and control the responses of the bridge.

“…Kong et al offered a new procedure of sub-structure method to long-span hybrid cable-stayed model bridges subjected to the vibrations due to vehicles [34]. A numerical investigation on the nonlinear vibration of inclined cables coupled with the deck in cable-stayed bridges was done by Kang et al [35]. It was indicated that the periodic variation of the cable tension induced by the deck vibration would cause the parametric resonance of the stay cable under certain tuning conditions.…”

Inclined hangers behave better than vertical ones under lateral loads (i.e., wind or earthquake) despite they are prone to fatigue phenomenon. In some instances, the slackness problem is seen in some inclined hangers, while others may become overstressed. By considering the modified hanger system, the disadvantages of vertical and inclined systems are resolved, while keeping their advantages. The objective of this study is to propose formulations for the optimum application of novel arrangement of hangers in a cable-arch bridge to suppress problems such as overstressing, force fluctuation, and decreasing the probability of fatigue phenomenon in hangers. To define optimum parameters, the modified hanger system was analyzed and compared with vertical and inclined ones considering nonlinear static analysis under dead load as an initial state plus seismic excitation and dynamic impact load of vehicles. Results indicate that the modified hanger system is improved remarkably in comparison with the inclined and vertical hanger systems.

“…They developed theoretical models for the vibrations of the cables subjected to support excitations, respectively. In general, vibration models can be classified into a single-cable vibration model (Lilien and Pinto Da Costa, 1994; Chen et al., 2002; Sun et al., 2003; Wu et al., 2003; Mei et al., 2007; Ying et al., 2007; Wang and Zhao, 2009; Kang et al., 2016; Ouni and Kahla, 2012; Brzakala and Herbut, 2014; Sun et al., 2014; Qian et al., 2014; Guo et al., 2016; Warminski et al., 2016) and cable-deck coupling vibration model (Luo et al, 2010; Kang et al., 2012; Sun et al., 2017). In addition, support excitations include the following: horizontal excitation at the upper support of the cable, vertical excitation at the lower support or axial excitation.…”

Owing to its excellent non-corrosiveness and fatigue resistance, a carbon fiber-reinforced polymer (CFRP) stay cable is an ideal alternative to overcome corrosion and fatigue problems associated with the traditional steel cable. However, stay cables are prone to various oscillations under wind, rain, and traffic loading. The vibrations of CFRP stay cables excited by periodic motions of the girder and/or pylons were studied and compared with those of steel cables. A nonlinear dynamic model for in-plane and out-of-plane vibrations of stay cables was proposed. Particularly, the geometrical nonlinearity of the cables was considered in this model. On the basis of this model, numerical solutions were obtained for CFRP cables and steel cables with the same conditions. Furthermore, the effects of important parameters on vibrations were discussed. These parameters included cable tensions, excitation amplitudes, and damping ratios. Results demonstrate that small excitation amplitudes may lead to forced vibrations or parametric vibrations with substantial amplitudes when natural frequencies of the cables are approximately half or one time of excitation frequencies. The maximal vibration responses of CFRP cables are weaker than those of steel cables when their lengths are substantial. As static tensions of the cables decrease, the “beating” frequencies and the maximal amplitudes of the vibrations increase.
