“…Sayyad AS and Ghugal YM (2019) [4] emphasize its enhanced ductility, which allows it to absorb energy and withstand larger deformations without failing. Arikoglu A and Ozturk AG (2020) [5] discuss UHPFRC's applications in both structural and architectural contexts, highlighting its ability to be used in thin, complex forms without compromising strength. This versatility opens up new design possibilities in architecture and construction.…”

“…Analytical methods are developed to investigate the dynamic performance of simple beams, plates and cylindrical shells damped with viscoelastic layer, 18–23 but due to the complexity of geometric configuration and boundary conditions of steel bridges, it will be an arduous task. The finite element (FE) modeling is a good approach, which has been widely applied to analyze the vibrational behavior of structures with viscoelastic layer.…”

“…With its excellent damping effect, CLD has been widely used in applications related to marines, vehicles and aerospace industries, but there is still a lack of its investigation and application in rail transit bridge engineering. 17 Analytical methods are developed to investigate the dynamic performance of simple beams, plates and cylindrical shells damped with viscoelastic layer, [18][19][20][21][22][23] but due to the complexity of geometric configuration and boundary conditions of steel bridges, it will be an arduous task.

This paper presents a combined method to predict structure-borne noise from the railway steel bridge deck damped with constrained layer damping (CLD), in which the frequency-dependent properties of the viscoelastic material are accurately considered through the iterative complex eigenvalue method (ICEM). Then, a 1:4 steel bridge deck model is designed and manufactured, and a series of hammer tests of the CLD-damped steel bridge deck are carried out in a semi-anechoic chamber to verify the proposed method. Then, the noise reduction effect of CLD is discussed in detail. It shows that the overall SPLs at the near field point S-3 and the far field point S-8 are reduced by 7.5 dB and 11.1 dB, respectively, and the noise attenuation rate along with distance is also improved significantly after damped with CLD. Finally, the influences of the key design parameters of CLD on noise reduction are quantitatively analyzed, so as to provide reference for the research and application of CLD in railway bridge engineering.

“…The results revealed that a good linear agreement exists between dynamic modulus of elasticity and static modulus of elasticity. Aytac Arikoglu and Ahmet Gokay Ozturk [23] presented a novel approach for evaluation of the damping and vibration analysis of arbitrarily curved laminated composite and sandwich beams. The results obtained were indicated that the present study is in very good agreement with the ones that exist in the literature.…”

Nowadays, the use of composite materials has taken a large place in civilian industries as well as in military and aerospace industries. Therefore, significant investigations about their mechanical and physical properties are needed. The present study addresses the effect of attached mass on damping ratio of symmetric angle ply laminate composite. Furthermore, factor influencing the effect of attached mass on damping ratio of laminate composite are studied using Taguchi method. The considered factors parameters are: attached mass locations from the clamped edge, stacking sequences and boundary conditions. The results of this study indicate that the damping ratio of the laminate composite plates is sensitive to the attached mass, where the damping ratio is found to be proportional to the locations of the attached mass. The findings of this study indicate that the attached mass decreases frequency parameter and increase the damping ratio of the composite plate, if it is inserted at a point other than a nodal line. In addition, the paper presents a good correlation between the numerical results of the fundamental frequency obtained by the ANSYS software and those obtained experimentally.
