“…To overcome the limitations of conventional passive TMDs, numerous alternatives have been proposed and investigated within recent years . Still within the passive range, a big research effort is now being directed towards nonlinear dissipative systems such as nonlinear energy sinks and especially particle impact dampers or its recent variation of particle TMDs (PTMDs) . While particle impact dampers have been widely used in aerospace and mechanical industries, it is not yet that common within civil engineering.…”

Summary This paper proposes an integrated damping system that aims at providing relatively high damping levels through the mobilization of a proportion of the structure's own mass. This offers significantly higher mass levels and, consequently, considerably more damping compared to conventional tuned mass dampers. Fluid viscous dampers are used to control accelerations in parallel with springs to resist the static loads applied to the moving mass. The advantages of employing relatively large mass levels in achieving considerable damping and reducing sensitivity to tuning are first analyzed using an idealized two degree of freedom structural representation. This is then followed by a description of the proposed “integrated damping system,” which is illustrated through a case study of a 250‐m tall building. The benefits of the proposed damping system are demonstrated through several numerical parametric assessments, as well as a selected suite of earthquake records. For the adopted case study, it is shown that, besides reducing the level of perceivable accelerations, the use of the suggested arrangement can offer an equivalent damping exceeding 50% of the critical damping, resulting in more than 40% reduction in the wind loads as well as over 60% reduction in displacement and acceleration response under seismic excitations.

“…However, the W-CSTC achieved a lower energy dissipation with narrower cycles, while the W-FTC was more favorable for the requirement of "no collapse under major earthquakes", which is the most important design criterion in Chinese Seismic Design Code. For this purpose, various energy dissipation devices can also be incorporated to increase structural seismic resistance [38][39][40][41][42].…”

Abstract:The reinforced concrete (RC) frames infilled with masonry walls are widely used in buildings. It has been well recognized that the arrangement of tie-columns can improve the wall integrity and seismic performance. However, the existing cast-in-situ tie-column (CSTC) has some problems, and a new type of fabricated tie-column (FTC) which can be recycled for secondary use is proposed in this study. Two specimens, the wall constrained by the cast-in-situ tie-columns (W-CSTC) and the wall constrained by the fabricated tie-columns (W-FTC), were designed and constructed. Low cyclic loading tests were carried out and some parameters, such as the failure modes, hysteretic curves and so forth, were used to evaluate the applicability of the FTC. The results show the W-FTC has a certain initial stiffness and strength, favorable deformation capacity, and the FTC can not only enhance the wall integrity to meet the functional requirements of tie-columns, but also solve the connection problems and reduce the adverse effects on the frame structure.

Summary A compound mass damper (CMD) was put forwarded based on the joint vibration control effects of tuned liquid damper and colliding particles. A series of shaking table tests were designed in order to investigate the dynamic response of a single degree of freedom bent frame structure with or without the damper (CMD, tuned mass damper, and tuned liquid damper) under three different kinds of earthquake waves. It is shown that the vibration reduction performance of CMD is generally better than the traditional dampers no matter from peak response attenuation rate or root mean square response attenuation rate. The vibration reduction effect of traditional dampers is susceptible to the characteristics of earthquake waves, whereas CMD is effective in a broader frequency bands. Also, the vibration reduction effect of CMD is not sensitive to the amplitude of earthquake waves, which means the system has good robustness. In addition, CMD has the advantage of fast start‐up. The numerical simulation results of the CMD are obtained through certain simplifications, and are in good agreement with the experimental results, which further verifies the damping effect of the proposed damper and provides a simplified method for its engineering design.
