Abstract: The problem of torsional harmonic vibration of circular surface and embedded foundations on cross‐anisotropic elastic half space is considered. Solution is achieved by proper transformations involving geometric and material ...

Abstract: A method of random vibration analysis of base isolated structures with hysteretic dampers is employed. The hysteretic restoring force is modeled by a nonlinear differential equation. The equations of motion for shear type ...

Abstract: The effect of frequency content of the ground excitation on the optimum design of a base isolation system and a first‐story damping system is investigated. The ground excitation is modeled as a filtered white noise with ...

Abstract: The problem of the optimal base isolation system of multistory shear type buildings has been considered in a probabilistic sense. For white noise ground accelerations the response of the structure relative to the base was ...

Abstract: A study of the effects of soil‐structure interaction on the dynamic response of linear base‐isolated structures is presented. The structures are supported at the surface of a homogeneous and viscoelastic half‐space and are ...

Abstract: In base‐isolated structures specially designed isolation systems provide the needed flexibility and energy dissipation capacity. The isolation systems, which can be either elastomeric or sliding systems, exhibit highly ...

Abstract: An experimental study, performed to evaluate the feasibility of using a sliding isolation system with uplift restraint devices for medium‐rise buildings subject to column uplift, is presented. A Teflon‐disc sliding bearing ...

Abstract: Torsion in base‐isolated structures with inelastic elastomeric isolation systems due to bidirectional lateral ground motion is studied. In a companion paper by the writers, torsional coupling in sliding base‐isolated ...

Abstract: The lateral‐torsional response of base‐isolated structures, with sliding isolation system due to bidirectional lateral ground motion, is studied. The objective of the study is to identify the key system parameters that ...
