Abstract: The purpose of this technical note is to present a time-domain formulation for linear hysteretic damping. The integro-differential equations that govern the dynamics of structures with linear hysteretic damping are transformed ...

Abstract: This paper presents a formulation for earthquake‐resistant design of hybrid isolation systems for base‐isolated floors and sensitive equipment mounted on a main structural system. Hybrid isolation techniques constitute a ...

Abstract: The paper proposes and studies a nonlinear mass damper that uses friction dampers acting transversely to the direction of the motion of the mass damper as a means for energy dissipation. The resistant scheme of this mass ...

Abstract: Experimental observations have shown that the dissipation per cycle in many materials does not depend on the deformation frequency over a wide frequency range. A linear model used frequently to represent this type of ...

Abstract: The effects of temperature on the energy dissipation of viscoelastic dampers for seismic mitigation of structures are investigated. To simulate the damper behavior, an evolutionary model is proposed to describe the dependence ...

Abstract: In this paper the causality of linear viscoelastic models with complex coefficients is examined. Such constitutive models have been found effective in describing the response of practical dampers and other dissipation ...

Abstract: The modal strain energy (MSE) method is a technique for approximate analysis of structures whose models in the frequency domain show frequency-dependent stiffness and damping matrices such as structures containing viscoelastic ...

Abstract: A class of nonlinear oscillator that scales input‐output relations is identified and studied in this paper. This type of system shows variable stiffness, variable damping, or both, and is piecewise linear in conical regions ...
