“…One method is to remove the broken cable element and use the equivalent functions. Hoang et al [14] and Olamigoke [22] simulated the cable breakage by using an impact waveform after removing the cable elements. Wolff and Starossek [16] and Park et al [7] simulated the cable breakage by using a transient load to the anchorage nodes.…”

“…ere is currently limited research on the duration of cable breakage. Fracture experiments were conducted by Mozos and Aparicio [13] on a seven-wire strand of a specific steel type; the result shows that the average rupture time is 0.0055 s. e impact fracture test by Hoang et al [14] on a single wire indicated that the duration of the cable breaking process is 0.017 s. Because the cable types differ for different bridges, the fracture duration varies.…”

“…Wolff and Starossek [16] and Cai et al [8] concluded, respectively, that the failure of one cable would cause significant bending moments in the stiffening girder but would not lead to a zipper-type progressive collapse. Hoang et al [14] pointed out that a progressive collapse would happen when four cables break in the studied cable-stayed bridge.…”

“…While dynamic analysis methods are recommended for simulation of cable breaking, some critical issues in the dynamic analysis procedure need further study, including the cable loss mode [9], cable loss duration [3,10], and the effect of the material and geometry nonlinearity [6,8,[10][11][12]. Some experimental studies have been conducted, such as the seven-wire steel strand specimen breakage experiment by Mozos and Aparicio [13] and the impact fracture test of a single steel wire by Hoang et al [14].…”

Cable-supported arch bridges have had many cable break accidents, which led to dramatic deck damage and even progressive collapse. To investigate the dynamic response and robustness of cable-supported arch bridges subjected to cable breaking, numerical simulation methods were developed, compared, and analyzed, and an effective and accurate simulation method was presented. Then, the cable fracture of a prototype bridge was simulated, and the dynamic response of the cable system, deck, and arch rib was illustrated. Finally, the robustness evaluation indexes of the cable system, deck, and arch rib were constructed, and their robustness was evaluated. The results show that the dynamic response of the adjacent cables is proportional to the length of the broken cable, while the dynamic response of the deck is inversely proportional to the length of the broken cable. The dynamic amplification factor of the cable tension and deck displacement is within 2.0, while that of the arch rib bending moment exceeds 2.0. The break of a single cable will not trigger progressive collapse. When subjected to cable breaking, the deck system has the least robustness. The proposed cable break simulation procedure and the robustness evaluation method are applicable to both existing and new cable-supported bridges.

The special collection on Cable Structures in Bridge Engineering is available in the ASCE Library (https://ascelibrary.org/page/jbenf2 /cable_structures_bridge_engineering). Cable structures are used extensively in bridge engineering, including stayed cables of cable-stayed bridges, main cable and suspenders of suspension bridges, and hangers of arch bridges. These types of cable structures can offer an elegant and economic bridge alternative. They have become a primary choice for long-span bridges throughout the world, and methods of designing and constructing them have developed rapidly during the last two decades. Accordingly, research on the design, analysis, inspection, and rehabilitation of these types of structures has become one of the most interesting and timely subjects in bridge engineering. The special issue of the Journal of Bridge Engineering is intended to promote and improve the analysis, design, inspection, and rehabilitation of cable structures. Twenty-three papers were selected for this special issue, including 15 technical papers, six case studies, and two technical notes. These papers present recent advances in the design, analysis, vibration control, damage detection, and evaluation methods of different types of cable structures, including cable-stayed, suspension, and arch bridges. There are three papers regarding the layout and detailed design of cable structures. A paper titled "Conceptual Design of a New Three-Tower Cable-Stayed Bridge System with Unequal-size Fans" by Shao et al. (2018) presents a new type of three-tower cable-stayed bridge with unequal-size fans. Numerical analysis of conventional and proposed systems showed that this new system is an excellent alternative to conventional designs regarding the stiffness, internal forces, and cost. In addition, it is fully accepted that cable anchorages in cable bridge structures are critical, yet there are no simple design and analytical methods available. Hence, Wei et al. (2018), in their paper "Full-Scale Specimen Testing and Parametric Studies on Tensile-Plate Cable-Girder Anchorages in Cable-Stayed Bridges with Steel Girder," present their investigations of different types of cable anchorages through test and analytical methods. Their research results are useful for bridge design and analysis as well as future research. Another paper, "Analytical Models on Frictional Resistance between Cable and Saddle Equipped with Friction Plates for Multi-Span Suspension Bridges" by Cheng et al. (2018), presents a practical method for evaluating the frictional resistance in structural designs of suspension bridges and quantifying the effects of friction plates in practice. The method was verified with experimental results. The authors also concluded that incorporating vertical or horizontal friction plates significantly increases the frictional resistance and that using one horizontal friction plate is more effective in enhancing friction resistance than using one vertical friction plate.
