Earthquake ground motions induced by a scenario event are spatially (partially) correlated and (partially) coherent. Simulated ground motion records can be used to carry out nonlinear inelastic time history analysis for a portfolio of buildings to estimate the seismic loss, which is advantageous as there is no need to develop and apply empirical ground motion prediction equations and the ductil...

Hysteresis is a highly nonlinear phenomenon, showing up in a wide variety of science and engineering problems. The identification of hysteretic systems from input-output data is a challenging task. Recent work on black-box polynomial nonlinear state-space modeling for hysteresis identification has provided promising results, but struggles with a large number of parameters due to the use of mult...

This study presents a precision stage driven by a piezoelectric actuator and equipped with a displacement magnification mechanism for the purpose of easy displacement measurement. The displacement magnification mechanism consists of flexible hinges and lever mechanisms. The developed stage is able to provide accurate measurement by virtue of the displacement magnification mechanism, but it is e...

-The performance of fuzzy logic (FLC) and PID controllers optimized by particle swarm optimization (PSO) for semi-active suspension system using magneto-rheological (MR) damper are investigated. MR damper is an intelligent damper filled with particle magnetic polarizable and suspended into a liquid form. The Bouc-Wen model of MR damper is used to determine the required damping force based on fo...

Piezo-actuated stage (P-AS) has become the topic of considerable interest in realm micro/nanopositioning technology recent years owing to its advantages, such as high positioning accuracy, response speed, and large output force. However, rate-dependent (RD) hysteresis, which is an inherent nonlinear property piezoelectric materials, considerably restricts application P-AS. In this research pape...

This research paper represents the analysis and simulation of semi-active suspension using non-linear modeling Magneto-Rheological (MR) with consideration hysteresis behavior for a quarter car model. The is based on assumption that each wheel experiences same disturbance excitation. Hysteresis analyzed Bingham, Dahl's, Bouc-Wen models. focuses passive, Dahl, models five road profiles. desired d...

Abstract This paper focuses on the optimum design of e-CLT technology. The technology consists in adding cross laminated timber (CLT) walls to an existing reinforced concrete (RC) infilled frame via asymmetric friction connection (AFC). authors carried out quasi-static and nonlinear dynamic analyses. RC is modeled OpenSees by fiber-section-based elements with force-based formulation. contributi...
