Abstract: The frequency dispersion characteristics of pile barriers are receiving more attention due to their effectiveness and a better understanding of their behavior at attenuating middle and lower frequency ground vibrations. ...

Abstract: One of the most important phenomena in periodic structures is the existence of the band of frequency gaps (BFGs). Elastic waves with frequencies in BFGs cannot propagate in the medium. Therefore, the BFGs can be used to ...

Abstract: Pile barriers have been broadly used to decrease the effect of ground vibration generated by machines or traffic. In recent years, the periodic theory of solid-state physics was introduced to study the reduction characteristics ...

Abstract: Pile barriers as an effective method for isolating ambient vibration have been used in practical engineering for many decades. However, the study of multiple rows of pile barriers in saturated soil is rare, especially of ...

Abstract: Extensive studies of pile barriers have been published in recent years. However, one important item in particular has been overlooked: the attenuation properties of multiple rows of piles embedded in fluid-saturated ...

Abstract: To respond to the urgent needs of verification, training, and drill for full scope severe accident management guidelines (FSSAMG) among nuclear regulators, utilities, and research institutes, the FSSAMG verification and ...

Abstract: This paper describes a prototype and analytical studies of a spherical rolling robot, a new design of a nonholonomic robot system. The spherical robot is driven together by an internal linear motor, continuously changing ...

Abstract: The mechanical performance of reinforced concrete beam-thin-wall joints under out-of-plane bending moments is studied and the analytical solutions in terms of stresses and rotational stiffness of the wall are obtained. For ...

Abstract: The dynamic responses of a structure with different foundations, including the so-called periodic foundation, are studied. Based on the calculation and optimization regarding the band of frequency gap of a periodic structure, ...

Abstract: Abstract Due to their attenuation zone characteristics, underground periodic barriers such as row piles used to isolate surface wave propagation in soil have been attracting increasing attention in recent years. However, ...
