“…Civil structures and infrastructure, in particular roadways and bridges, have multiple lifelong obstacles caused by various reasons of environmental impact such as corrosion, microstructural defects, cracks, thermal and residual stresses, instability, bond failures, or natural disasters such as earthquake and flood [1][2][3]. Damage to structural elements affects structural properties such as mass, stiffness, and damping, resulting in changes in the dynamic response of the structure such as natural frequency, modal shape, and damping ratio [4][5][6][7][8][9]. Therefore, actual solutions can play an essential role in ensuring the safety and reliability of structures.…”

“…Seismic activities can induce structural and non-structural damage both during and afterwards the event, which is mainly caused by perturbations in load-resisting elements of constructions, such as load-bearing walls and columns [1,2]. In most cases, seismic failures in structures are triggered by their limited resilience owing to deficient component size, material properties, and lack of structural flexibility or ductility [3,4].…”

The behavior of masonry shear walls reinforced with pseudoelastic Ni–Ti shape memory alloy (SMA) strips and engineered cementitious composite (ECC) sheets is the main focus of this paper. The walls were subjected to quasi-static cyclic in-plane loads and evaluated by using Abaqus. Eight cases of strengthening of masonry walls were investigated. Three masonry walls were strengthened with different thicknesses of ECC sheets using epoxy as adhesion, three walls were reinforced with different thicknesses of Ni–Ti strips in a cross form bonded to both the surfaces of the wall, and one was utilized as a reference wall without any reinforcing element. The final concept was a hybrid of strengthening methods in which the Ni–Ti strips were embedded in ECC sheets. The effect of mesh density on analytical outcomes is also discussed. A parameterized analysis was conducted to examine the influence of various variables such as the thickness of the Ni–Ti strips and that of ECC sheets. The results show that using the ECC sheet in combination with pseudoelastic Ni–Ti SMA strips enhances the energy absorption capacity and stiffness of masonry walls, demonstrating its efficacy as a reinforcing method.

“…Lately published review papers on cable vibration and control have paid attention to different aspects of the topic. Jafari et al (2020) presented a comprehensive review of wind-induced vibrations, Javanmardi et al (2022) focused on vibration control techniques and devices, Chen et al (2022) pointed out three main problematic cable vibrations to be resolved at present, and Caetano (2021) summarized fundamentals of cable dynamics, wind-induced cable vibrations, and also introduced common mechanical dampers for cables. In contrast, the present paper focuses on the development of schemes and techniques for supplementing cable damping and theoretical investigation of the damped system, with emphasis on the recent practice particularly in China.…”

Stay cables in cable-stayed bridges are subjected to various types of dynamic excitation mechanisms under environmental loads. The excited vibrations can have a large amplitude because of low vibration frequencies and small inherent damping of cables. As cables become longer (the longest cables are around 600 m in cable-stayed bridges with a main span of 1000 m), more modes are vulnerable to wind and rain-wind induced vibrations, posing challenges to vibration mitigation. This paper presents a comprehensive review of recent advances in stay cable vibration mitigation, including theoretical modeling of cable damping system and techniques for enhancing multimode damping. Recent results on cable damping measurements, understanding of cable vibrations, and relevant aerodynamic countermeasures are also recalled. The reflections can provide guidance for cable vibration control design of cable-supported bridges and for the maintenance/upgrade of cable vibration mitigation system of existing bridges.
