Earthquake Response of Systems with Bilinear Hysteresis

Journal of the Structural Division, 1964
A spectral study of the behavior of systems subjected to earthquakes is presented, in which single degree of freedom systems with elasto-plastic and bilinear hysteresis are considered. The system parameters that varied are natural period, damping, yield strength, and strength characteristics. The results, presented in graphical and tabular form, permit

Sinusoidal Excitation of a System With Bilinear Hysteresis

Journal of Applied Mechanics, 1960
Many physical systems exhibit hysteresis which may be adequately described by a bilinear hysteresis model. This paper considers the response of such a system to sinusoidal excitation. It is shown that the system exhibits a soft-type resonance with stable, single-valued response curves. For such a system it is shown that there exists a critical value of

Vibration of Frame Foundation With Bilinear Hysteresis for Rotating Machinery

Journal of Engineering for Industry, 1974
The vibration of a single-story frame with bilinear hysteresis supporting a rotating machine is analyzed. The excitation force caused by the rotating unbalanced mass of the machine has a frequency dependent amplitude. The bilinear hysteresis of the resisting force of the frame to the motion is derived from the bilinear moment-curvature relationship of ...

On Friction Damping Modeling Using Bilinear Hysteresis Elements

Journal of Vibration and Acoustics, 2002
Massless bilinear hysteresis elements are often used to model frictional energy dissipation in dynamic systems. These quasi-static elements possess only two describing parameters, the damper stiffness and the force at which it slips. Bilinear hysteresis elements capture the qualitative nature of friction-damped forced response, but sometimes have ...

Parametric resonance of a single-degree-of-freedom system with double bilinear hysteresis

International Journal of Non-Linear Mechanics, 1971
Abstract A simple pendulum with a hinge of double bilinear hysteretic restraining moment-rotation characteristic under parametric excitation is studied. In contrast with a linear system with viscous damping, a double bilinear hysteretic system leads, in general, to finite response under parametric resonance.

The Response of an Oscillator With Bilinear Hysteresis to Stationary Random Excitation

Journal of Applied Mechanics, 1978
By applying the technique of stochastic averaging, a simple analytical result is obtained for the joint distribution of the displacement and velocity of a bilinear oscillator excited by a stationary random process. A comparison of theoretical results deduced from this distribution with corresponding digital simulation results shows that the theory is ...

Capability for Growth in Nonlinear Response of SDOF With Bilinear Hysteresis

Volume 8: Seismic Engineering, 2009
To approximate nonlinear response of structures subjected to an earthquake excitation, the displacement method in U.S. or the energy method in Japan has been practically used. However, unless these methods include the nature of dynamics of nonlinear structure well, the nonlinear response is not adequately calculated.

Optimum characteristic properties of isolators with bilinear force–displacement hysteresis for seismic protection of bridges built on various site soils

Soil Dynamics and Earthquake Engineering, 2011
Abstract In this study, closed form equations as functions of the isolator, bridge and ground motion properties are formulated to calculate the optimum characteristic strength, Q d and post-elastic stiffness, k d , of the isolator to minimize the maximum isolator displacement (MID) and force (MIF) for seismic isolated bridges (SIBs).
