“…As the FEM used is 2D, the cables of the model represent the combined capacity of the two cable planes of the real bridge. The mechanical properties of the deck and towers are summarized in Cid et al [15]. The permanent loads applied to the FE model are the structural deck weight (DC = 146 kN/m), the weight of the non-structural elements of the deck (DW = 54 kN/m) and the cable prestressing forces (PS).…”

“…The volume of the cable-system in the real bridge corresponds to 759 m 3 . In a previous work [15], the optimization of the intact model was performed, resulting in a volume of 634.15 m 3 , which corresponds to a reduction of 16.45%.…”

“…To obtain the global optimum, Cheng (Cheng 2010) firstly applied the genetic algorithm combining the FE method in the optimum design of steel truss arch bridges. After that, some other optimization algorithms also have been utilized in cable forces optimization, for example, the multi-objective genetic algorithm (Cai and Aref 2015), the particle swarm optimization (PSO) (Chen et al 2015;Cao et al 2018), the micro-genetic algorithm (Ha et al 2018), the simulated annealing (Guo et al 2019), the sequential quadratic programming algorithm (Cid et al 2018), and the enhanced artificial bee colony algorithm (Latif and Saka 2019). These optimization algorithms, especially the metaheuristic optimization algorithms, often require a considerable number of structural response evaluations in the iteration process, which makes these approaches inefficient, especially for the FE-based structural response evaluation approach.…”

“…The most representative is the large lateral vibration of the Millennium Bridge in London, which has gained considerable attention since its occurrence. Some characteristics of pedestrian synchronization rate were obtained in the occurrence of lateral vibration through the study of T-bridge in Japan (Cid et al , 2018; Caetano et al , 2017; Ingólfsson et al , 2012; Fujino et al , 1993). The structural vibration response characteristics under different pedestrian densities and synchronization rates were obtained through experiment of the footbridge at Singapore Changi Airport (Bursi et al , 2014; Lievens et al , 2018; Ricciardelli and Demartino, 2016; Vladimir et al , 2017).…”
