Abstract: Tables of impedance functions and effective input motions for rigid square foundations embedded in a uniform elastic half‐space are presented. The tables include numerical results obtained by a hybrid approach for embedment ...

Abstract: A method to obtain the response of a rigid circular foundation resting on a uniform elastic half‐space and subjected to a spatially random ground motion is presented. The solution of the resulting mixed boundary‐value ...

Abstract: Linearized continuum models of a suspended span with unloaded backstays and of a symmetric three-span suspension bridge are used to study the effects of the flexibility of the hangers on the vertical vibrations of suspension ...

Abstract: The paper focuses on the representation of a classical damping matrix in terms of a Caughey series including only negative or zero powers of ([m]−1[k]). An explicit expression for the series in terms of prescribed modal ...

Abstract: The dynamic impedance functions for a rigid hemispherical foundation embedded in a uniform viscoelastic half‐space are obtained by an integral equation approach. Numerical values for the vertical, torsional, horizontal, ...

Abstract: In this paper, we examine the use of boundary springs as approximate external boundary conditions for the typical soil islands encountered in finite-element (FE) models of soil–foundation interaction problems. We present ...

Abstract: Forced‐haimonic‐vibration tests, using an eccentric‐mass shaker, were conducted on two small but different concrete foundations. One foundation (Cholame 1E), located in central California, consisted of a 4‐in.–(10‐cm‐) ...

Abstract: Shake table tests were undertaken on a full-scale wind turbine (65-kW rated power, 22.6-m hub height, and 16-m rotor diameter) using the Network for Earthquake Engineering Simulation Large High Performance Outdoor Shake ...
