Equivalent Linearization for Hysteretic Structures

Axial Hysteresis Behavior with End Restraints
Parametric study of axially loaded steel members with symmetrical rotational end springs (connections) was performed. The main parameters are the connection flexural strength, the effective...

Inelastic Response of Restrained Steel Tubes
Eighteen specimens made from 1 in. (25-mm) square tubes with welded gusset plates were tested under repeated axial loading. Length of the specimens varied from 20 in. to 54 in. (510mm...

Prediction of Hysteresis of Reinforced Concrete Members
The endochronic theory for inelasticity and failure, previously established, is used to predict the response of reinforced concrete beams in cyclic bending at large strains. Cross sections...

Densification and Hysteresis of Sand under Cyclic Shear
The accumulation of inelastic strain due to the irreversible rearrangement of grain configurations associated with deviatoric strains is characterized by a nondecreasing material variable,...

Stationary Random Vibration of Hysteretic Systems
A more rigorous derivation of the modified power balance method is given for general yielding systems. It is demonstrated that the physical meaning of the equivalent linearization criteria...

Steady-State Response of Yielding Shear Structure
An approximate analytic technique is used to investigate the steady-state response of a continuous shear beam including both yielding and viscous dissipation. The yield model is one which...

Analysis of Infiltration into Draining Porous Media
Numerical analysis was applied to the inundation of a draining sand column. A method was proposed whereby hysteresis could be considered. For Botany sand, after periods of short drainage...

Inelastic Response for Arbitrary Histories of Loads
The paper presents procedures for calculating the inelastic response of prismatic segments subjected to arbitrary histories of loads and deformations. Included are the effects of nonlinear...

Intermittent Infiltration into Soils with Hysteresis
A method is presented to solve the differential equation describing vertical flow in partly saturated soils. A high-speed digital computer was used to obtain solutions for different initial...

Response of Multi-Degree-of-Freedom Yielding Systems
The steady-state frequency response equations for a class of multi-degree-of-freedom yielding structures are determined using approximate analytic techniques. The yield model used is a...

Inelastic Earthquakes Response of Tall Steel Frames
A procedure for evaluating the lateral response of unbraced multistory building frames subjected to a prescribed base motion was developed for use on a digital computer. A Ramberg-Osgood...

Comparison of Static and Dynamic Hysteresis Curves
Hysteretic force-deflection curves of a single-story laboratory structure made of mild structural steel were obtained experimentally for both static and dynamic loading conditions. The...

Earthquake Response of Systems with Bilinear Hysteresis
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....

Earthquake Response of Systems with Bilinear Hysteresis
A spectral study of the behavior of systems subjected to earthquakes is presented, in which single degree of freedom systems with elasto-plastic and system parameters that varied in this...
