Abstract:
In recent years, there has been an increase in high-magnitude earthquakes, which has led to a need for research on seismic protection and its importance in safeguarding structures such as buildings and bridges. Adding supplementary damping to the structure can help reduce dynamic responses and base shear demand. Energy dissipation devices such as fluid viscous dampers (FVDs) are often used to mitigate structural sway during seismic activity. The proposed thesis aims to study the effect of a viscous damper on the seismic performance of RCC-framed buildings. In this study, 3-D models of Four and

Abstract:
This article studies the energy dissipation mechanism of a proposed magneto-solid damper using a three-dimensional finite element model developed in COMSOL Multiphysics software. The energy dissipation mechanism of the magneto-solid damper dissipates energy through combined actions of friction and eddy current damping. The key components of the magneto-solid damper are a steel plate, two copper plates placed on two sides of the steel plate in parallel, and two planar arrays of permanent magnets each one placed between the steel plate and one of the copper plates. These arrays are kept away fro

As tall buildings keep becoming taller, they become more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) are discussed. A symmetrical moment resistance frame (MRF) twenty storey three-dimensional model were modeled in SAP2000 and a TMD was placed on its top and through it to study its effects on the structural response due to seismic excitations and using time history analysis with and without the TMD. The study indicates that the response of structure such as storey displacements

This paper focuses on viscous dampers disposition schemes regarding the vibration control of the Mega-Sub Controlled Structure System (MSCSS) subjected to rare earthquake excitation. It is intended in this study to evaluate the dynamic characteristics of the MSCSS compared with the traditional mega frame structure. The optimum arranging scheme matched with dynamic characteristics of MSCSS is given by analyzing the dynamic responses of the structure with different arrangements of viscous dampers on structure.

Abstract:
Triangular added-damping-and-stiffness (TADAS) dampers are reliable passive control devices for earthquake-excited buildings. The arrangement of TADAS dampers in buildings is essentially the allocation of triangular energy dissipation plates (TEDPs) among different stories, which directly influence the passive control effect and the construction cost. This paper proposes four iterated methods to achieve the optimum arrangement of TADAS dampers for seismic drift control of buildings, including the regular iterative method (RIM), the accelerated iterative method (AIM), and two modified accelerat

Abstract:
Particle damper is formed by granular particles enclosed in a container which is attached to or embedded in a vibrating structure. The energy dissipation mechanism of a particle damper is highly nonlinear, and derived from a combination of collision/impact and friction among particles and between particles and the enclosure. Meanwhile, the coupling between particle dampers and the host structure and among multiple dampers further increases the difficulty to analyze the particle damping performance. In this paper, a new coupling method is developed to integrate the continuous host system with m

The vibration amplitudes of bladed disk assemblies can be reduced significantly by means of friction damping devices such as shrouds, damping wires and interblade friction dampers. In practice, interblade friction dampers are applied in rotating arrangements with various geometries showing curved or flat surfaces like so-called wedge-shaped dampers. This paper is focusing on a computation method to predict the dynamical behaviour of turbine blades with friction dampers including both, curved and wedge-shaped dampers with Hertzian and non-Hertzian contact conditions, respectively.

Abstract The combustors of many modern land-based gas turbines and aero-engines are annular. This kind of combustors often suffer from thermoacoustic oscillations, with the occurrence of mostly the circumferential first-order, second-order and third-order oscillation modes in the annular combustion chamber. This could cause severe pressure oscillations in the combustor, which may increase noise and NOx emissions, affect the safe operation of the engine and even cause irreversible damages to the structure. To solve this problem, passive control methods are widely used — adding passive acoustic

Abstract In this study, a single-degree-of-freedom structure with multiple nonlinear tuned mass dampers is investigated. A sinusoidal excitation is assumed to be applied to the structure. In order to obtain the results, a nonlinear mathematical model of the general system is obtained in the form of a set of nonlinear ordinary differential equations. Dry friction and cubic stiffness nonlinearities are considered for the nonlinear terms. To obtain steady-state frequency responses of the system, these nonlinear ordinary differential equations are transformed into a set of nonlinear algebraic equa
