“…The particles were equally divided and placed in each of the four compartments without any order. The number of particles and their size were selected in order to obtain the aforementioned FAR values, creating a single layer of particles which is recommended for structures with low natural frequency (Papalou 2018). The motion of the structure was measured by a laser transducer and an accelerometer, while the motion of the base was measured by a draw-wire sensor and an accelerometer (Figure 1).…”

“…Several passive control systems have been used in past studies to attenuate vibrations of structures and machines. Particle dampers belong in these systems, and their attractiveness [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] is based on their simplicity, low cost, and effectiveness in reducing the dynamic response of mechanical systems and machines. Lately, their use has been extended in the civil engineering area [17].…”

An experimental study was performed examining the effectiveness of a multi-compartment damper in attenuating the response of structures under random and earthquake excitations. The damper consisted of four compartments of unequal size; it was mounted on a small one-story steel structure. The same number of steel spherical particles were placed inside each compartment, resulting in filling area ratios (the total area of the squares around the projected particles divided by the area of the compartment) from 40% to 70%. The damper was effective in reducing the response displacement and acceleration of the structure considerably. The use of different filling area ratios enabled the damper to be effective for a wide range of excitation levels.

“…These dampers have been used in applications in many fields. Papalou et al [61,62] used the particle damper to enhance the seismic performance of classical columns at historical monuments. Lu et al [63] proposed a modified approach based on the discrete element method to simulate the behavior of the particle damper system and compared its vibration control effectiveness with a suspended TMD [64].…”

The pounding tuned mass damper (PTMD) is a novel vibration control device that can effectively mitigate the undesired vibration of subsea pipeline structures. Previous studies have verified that the PTMD is more effective and robust compared to the traditional tuned mass damper. However, the PTMD relies on a viscoelastic delimiter to dissipate energy through impact. The viscoelastic material can be corroded by the various chemical substances dissolved in the seawater, which means that there can be possible deterioration in its mechanical property and damping ability when it is exposed to seawater. Therefore, we aim to conduct an experimental study on the impact behavior and energy dissipation of the viscoelastic material submerged in seawater in this present paper. An experimental apparatus, which can generate and measure lateral impact, is designed and fabricated. A batch of viscoelastic tapes are submerged in seawater and samples will be taken out for impact tests every month. Pounding stiffness, hysteresis loops and energy dissipated per impact cycle are employed to characterize the impact behavior of the viscoelastic material. The experimental results suggest that the seawater has little influence on the behavior of the viscoelastic tapes. Even after continuous submersion in seawater for 5 years, the pounding stiffness and energy dissipation remains at the same level.

“…The dynamic behavior of multi-drum columns is highly nonlinear and cannot be estimated easily with analytical methods. Previous research that examined the dynamic response of these complex structures was based either on experimental work on scaled-models or simulations with finite elements, finite differences, boundary elements and distinct elements [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These studies focused mostly on three-dimensional models that can better simulate the rotation of the drums around the vertical axis and the out of plane motion.…”

Ancient temples consisting of classical columns have been exposed through the years to dynamic loads with sometimes detrimental effects. Predicting their dynamic behavior is important for their restoration and preservation. This paper analyzes the behavior of classical columns under dynamic loading using simplified two-dimensional finite element models. The adequacy of these models for the prediction of the dynamic behavior of classical columns is verified comparing the numerical results with experimental measurements. The most important parameters that influence the model's behavior are identified. The behavior of classical columns can be predicted in the direction of excitation with reasonable accuracy using two-dimensional finite element models when the properties of the models are selected appropriately.
