“…A large amount of recent research on PTMD show that PTMD is highly effective at suppressing vibrations excited by harmonic excitations, vortices, earthquakes, or complex loads underwater (Jiang et al, 2017; Wang et al, 2018b). PTMD can suppress vibration of various structures including pipelines, (Song et al, 2016) cable-stayed bridges (Zhang et al, 2021b) and hollow structures (Duan et al, 2020; Zhao et al, 2020). In order to employ PTMD in large-scale structures, multi-PTMD (Northern MarianasTMD) was introduced (Lin et al, 2016; Wang et al, 2021).…”

The pounding tuned mass damper (PTMD), which is a passive vibration control device, has attracted much attention in recent years. However, due to the absence of additional dampers in traditional PTMD, the free vibration of structures cannot always be suppressed quickly. Another limitation for the traditional PTMD is that the primary structure is subjected to a large pounding force that may cause local damage and fatigue. To address these limitations, this paper proposes a novel PTMD with constrained layer damping (CLD-PTMD) by attaching a damping layer and the constraining layer to the surface of the stiffness element of the PTMD to provide more damping. In the experiment, the influence that the different configuration parameters have on the damping performance of CLD is examined. A shake table test is conducted to investigate the energy dissipation of a CLD-PTMD subjected to harmonic excitation. The FEM model of the CLD beam is established to determine the damping ratio and analyze more parameters. The CLD-PTMD is used for the vibration control of a simulated SDOF structure. The results demonstrate that compared with the traditional PTMD, CLD dissipates more energy than the pounding process. In addition, CLD-PTMD has a lower pounding force and pounding energy than PTMD in free and forced vibration. The free vibration with CLD-PTMD can be suppressed faster. The robustness of CLD-PTMD is better and the control performance of CLD-PTMD is more stable than traditional PTMD.

“…Structural safety, within the seismic context, can be effectuated via appropriate vibration control and mitigation mechanisms [1,2,3]. The design of such devices is subjected to particular requirements with respect to the frequency content of the seismic input, which usually lies at the lower range, as well as to the aspect of dealing with protected systems of large mass [4].…”

Structures should adhere to capacity and serviceability requirements that can be compromised by dynamic excitation. Structural vibration mitigation aims to ensure serviceability and guarantee safety, but often suffers from limitations of the enabling devices; usually preferred to follow a passive scheme. The current study harnesses the potential of nonlinear mechanisms to amplify the vibration mitigation effects. A geometrically nonlinear device is proposed, called NegSV, which is mounted on a frame structure, without requirement of an additional tunable mass mechanism. The nonlinear configuration l eads t o n egative stiffness phenomena, which can be exploited for guiding the input energy toward specific structural elements. The dynamics of the system and its efficacy in terms of vibration attenuation is studied via nonlinear finite element analyses under base e xcitation. The seismic input is additionally parametrized in order to allow for a probabilistic assessment of its influence o n t he performance of the device, via use of Monte Carlo simulations. The probabilistic distributions of associated structural integrity metrics are calculated on the basis of assumed distributions of the input parameters. The respective results for both the unprotected and protected structures are compared, revealing effective vibration mitigation potential for critical system components, such as the base of the structure, relieving base shear. 1016COMPDYN 2023 9 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.

“…In early studies of the mass block is located in the middle of the two delimiters but, parametric studies revealed that the gap is the key parameter that influences the vibration control effectiveness. After that, Zhang et al ( 2021) [8] proposed a new type damping device named asymmetric (PTMD) where two gaps of the APTMD can be set to different values. Results showed that, the APTMD is slightly better than the TMD and the PTMD.…”

Enhancing the seismic performance of cable stayed bridges (CSBs) gained increasing attention over the past few decades. The aim of this paper is to investigate how single tuned mass damper (TMD) can enhance the performance of CSB by comparing the performance of the CSB before and after incorporating the TMD under different excitation records. Finite element analysis has been performed and verified in order to assess the optimum value of TMD mass ratio. Results shows that, the presence of TMD leads to a noticeable improvement in different responses. Also, for mass ratio values between 0.25% and 0.5%, the bridge shows best performance.
