Special Issue Information

Dear Colleagues,

Civil engineering structures, like bridges, high-rise buildings, chimneys, stay cables, and wind turbines, are prone to vibrations when subjected to dynamic loads, e.g., passing vehicles, pedestrians, wind, sea waves, and earthquake loads, which may cause structural failure, discomfort to occupants, and the malfunction of the installed equipment. Hence, the mitigation of structural vibrations has always been a major concern amongst structural engineers. One of the effective means to reduce the dynamic response of tower-like structures is the application of vibration damping devices, e.g., tuned dampers. In practical applications, passive, semi-active, and active vibration control systems are used.

In addition, vibration isolation systems are applied to different kinds of engineering structures, e.g., basements of buildings, railway tracks, or the foundations of scanning electron microscopes, to mitigate the vibration energy transfer from the ground-excited base to the structure to be vibration-isolated.

This Special Issue is aimed at providing selected contributions on vibration damping and isolation systems for civil engineering applications. Potential topics include, but are not limited to, the following: the development of vibration control systems; the development of vibration isolation systems; novel passive, semi-active or active tuned dampers; base isolation systems; the application of vibration control systems to CE structures; the application of vibration isolation systems to CE structures; smart structures; smart components; the damping of earthquake-induced vibrations; the damping of wind-induced vibrations; the damping of train-induced vibrations; the damping of pedestrian-induced vibrations; mechanical inverter; semi-active dampers; and active dampers.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

During strong earthquakes, pounding may occur on large-span bridges and their approach bridges. The effect and mitigation measures of such pounding have rarely been explored in previous studies. This paper primarily uses finite element models to investigate the pounding effects at the expansion joints between the main cable-stayed bridge and its approach bridge. Friction pendulum bearings (FPBs) and fluid viscous dampers (FVDs) are used to alleviate poundings. Furthermore, a detailed analysis is conducted on how the pounding effect of the isolated main bridge with FPBs and FVDs is affected by the wave passage effect, ground motion type, and soil type. This study reveals that FPBs and FVDs can effectively reduce pounding effects and the associated risks. Even with the installation of FPBs and FVDs, lower seismic wave velocities and near-fault seismic motions with pulse effects can significantly increase the pounding effects between the cable-stayed bridge and its approach bridge.
