Abstract: Interaction between piles, known as pile‐soil‐pile interaction or group effect, modifies both group stiffness and damping and, consequently, affects the dynamic properties and behavior of the offshore tower. The formulation ...

Abstract: Three-dimensional transient response of both massless and massive multiple, rigid foundations, bonded to an elastic, homogeneous half-space, is investigated to study the effect of dynamic interaction ...

Abstract: A closed-form solution of transient response to suddenly applied loading distributed over a rectangular area on the surface of an elastic homogeneous half-space is developed for special purposes ...

Abstract: A recently developed technique for the digital simulation of spatially incoherent seismic ground motions is extended to include two or three spatial coordinates. This extended approach allows for four situations: (1) ...

Abstract: Dynamic pile-soil-pile interaction is analyzed using dynamic interaction factors. For pile groups, complex stiffness matrices are formulated in closed form for excitation in all vibration modes ...

Abstract: Two techniques for the artificial generation of spatially incoherent Gaussian seismic ground motions are proposed and validated. The simulated motions are homogeneous and stationary, and may be one‐, two‐, or three‐dimensional ...

Abstract: When calculating dynamic response of embedded foundations or piles, impedances (stiffness and damping) of the adjacent soil are needed. To account approximately for soil nonlinearity under high strain, contact deficiencies ...

Abstract: A one-dimensional finite difference numerical method is applied for the simulation of sound attenuation in reactive silencers placed in an impedance tube configuration. This time-domain approach ...

Abstract: The acoustic wave attenuation performance of Venturi tubes with zero mean fluid flow is investigated by: (1) combining analytical solutions for one-dimensional wave propagation in conical reducers, ...
