Abstract: In this paper the “causal hysteretic element” is constructed and analyzed. The dynamic stiffness of the proposed hysteretic model has the same imaginary part as the “ideal” hysteretic damper, but has the appropriate real ...

Abstract: The problem of viscous heating of fluid dampers is examined in this paper at the limit of small-amplitude motions where the heat transfer equation becomes linear. At this limit, a one-dimensional energy equation expressed ...

Abstract: In this paper, the basic transfer functions and time-response functions of linear phenomenological models are revisited. The relation between the analyticity of a transfer function and the causality of the corresponding ...

Abstract: In this paper the plastic torsional buckling of a cruciform column is revisited. The interest in this classical problem resurfaced from a practical application in the area of seismic protection of structures. The theoretical ...

Abstract: Motivated by the growing interest in suppressing vibrations with supplemental rotational inertia, this paper examines and constructs the basic frequency-response functions and subsequently derives the corresponding causal ...

Abstract: This paper investigates the inelastic response of a yielding single-degree-of-freedom oscillator coupled with a rocking wall. Configurations of both a stepping rocking wall and a pinned rocking wall that have been reported ...

Abstract: This paper presents a case study on the seismic response of a recently constructed freeway overcrossing located in southern California, which is equipped with elastomeric bearings and fluid dampers at its end abutments. ...

Abstract: This paper examines the transient rocking response of anchored blocks subjected to physically realizable horizontal pulse-type motion. Restrainers with elastic-brittle and elastic-plastic behavior are considered. Under ...
