Field tests of rock-socketed monopile in coastal area subjected to lateral cyclic loading

Lingyun Feng et al.

Summary: Field tests were conducted to investigate the behavior of rock-socketed monopile under lateral cyclic loading in coastal areas. The studies measured the displacement, stiffness, and bending moment of the pile under different cyclic loading conditions. The test results showed that small amplitude cyclic loading had an impact on the displacement and stiffness degradation, while the bending moment increased with the number of cycles. Moreover, the rate of displacement accumulation, stiffness degradation, and bending moment variation were found to be smaller in weathered rock layers compared to sand or clay foundations. Furthermore, the hysteresis behavior of shallow and deep cyclic p-y curves was explored. Finally, the lateral bearing performance of the rock-socketed monopile was found to degrade significantly after 3000 cycles of lateral cyclic loading through static load tests.

Active Metadamping: A phenomenon of damping enhancement in metamaterial via feedback control

Kamal K. Bera et al.

Summary: This paper introduces the concept of metadamping and its application in acoustic metamaterials. The use of active feedback control enhances the energy dissipation capability of the metamaterials. The study shows that velocity feedback control provides the highest total damping ratio, but at the expense of reduced attenuation bandwidth. Additionally, it is possible to achieve high damping in stiff metamaterials through active control.

Spectral element formulation for rock-socketed mono-pile under horizontal dynamic loads

Rishab Das et al.

Summary: This study thoroughly investigates the dynamic response of a mono-pile foundation in homogeneous soil and varied layered soil-rock conditions under horizontal dynamic loads. The frequency dependent stiffness and damping of a mono-pile foundation embedded in layered elastic half space are developed. The changes in stiffness and damping with frequency for various soil-rock systems and the influence of depth of the rock-socketed pile on the dynamic response characteristics are demonstrated.

Numerical study of seabed response and liquefaction around a jacket support offshore wind turbine foundation under combined wave and current loading

Shu-xin Wei et al.

Summary: This study used numerical simulation to analyze the process of seabed liquefaction under wave-current conditions. It was found that in the absence of current, the depth and range of the liquefaction area around the foundation increased and then decreased as the wave propagated. Under current conditions, the liquefaction depth was greater. Additionally, the study found that downstream piles were more prone to liquefaction than upstream piles in the presence of forward current.

Metadamping in inertially amplified metamaterials: Trade-off between spatial attenuation and temporal attenuation

Mahmoud I. Hussein et al.

Summary: Metadamping, the enhanced or diminished intrinsic dissipation in a material, can be achieved by designing the internal structure of the material. By coupling inertially amplified metamaterial with locally resonant metamaterial, a trade-off between spatial attenuation and temporal attenuation can be achieved within a certain range.

Lateral static stiffness of offshore monopile socketed in soft rock

Rui He et al.

Summary: This paper investigates the lateral static stiffness of monopiles in soft rocks under different scenarios through laboratory-scale model tests and numerical analyses. The load-sharing mechanisms of monopiles are found to be significantly influenced by the rock-bearing layer. It is recommended to use p-y curves obtained by piecewise fitting for soil and rock layers or three-dimensional finite element model in the modeling of rock-socked piles.

Dynamic Responses of Embedded Rock Pile Groups due to Rock Burst considering Coupled Pile-to-Pile Interaction

Xiaolin Cao et al.

Summary: This note presents an analytical solution to study the dynamic behavior of pile groups embedded in rock due to rock burst, taking into account the interaction between piles. Energy generated by the rock burst propagates through the soil in the form of stress waves and is transmitted to the pile foundation through the interaction between the soil around the pile and the pile. For rock-socketed piles, the condition of pile tip fixing is considered. The horizontal dynamic response calculation model of the pile group is established, and the analytical forms of pile group stiffness and pile group interaction factor are obtained. Additionally, the effect of saturated soil parameters on the dynamic response of pile groups is discussed.

Metadamping enhancement and tunability via scissor-like electromechanical metamaterials

Hasan Al Ba'ba'a et al.

Summary: This study reports a novel electromechanical metamaterial called SEMM, which utilizes its electromechanical resonant effects to achieve enhanced and tunable damping properties. The scissor-like structure in SEMM amplifies the damping ratio through a displacement amplification mechanism, improving vibration mitigation. By quantifying the relative dissipation performance based on complex band structures, SEMM demonstrates higher damping performance compared to traditional systems through numerical verification and analysis. The electromechanical nature of piezoelectric material in SEMM allows for convenient tuning of the damping properties by adjusting the piezoelectric shunting circuit.

Summary: This paper investigates the relationship between the bearing capacity of rock-socketed piles in soft rock areas and the vertical restraint stiffness at the pier bottom, proposing a novel method for evaluating pile foundation bearing capacity. By analyzing the impact of parameters and conducting field dynamic tests, the accuracy and effectiveness of the method were verified. The results show small differences between the analytical solution and numerical simulation, indicating the new method's accuracy.
