Hyperbolic Tangent Model (Version 2) for 200 kN LargeScale MagnetoRheological Fluid (MR) Damper
03 Jun 2012  Computational Models  Contributor(s): Zhaoshuo Jiang, Richard Christenson
The MagnetoRheological (MR) fluid damper is a promising type of semiactive device for civil structures due to its mechanical simplicity, inherent stability, high dynamic range, large temperature operating range, robust performance, and low power requirements. The MR damper is intrinsically...

This Model presents a representation of a 9 story and 9 degree of freedom model for a building excited by and earthquake input.

Evaluation of the 9Story Benchmark Building Shear Model
24 Jan 2012  Computational Models  Contributor(s): Amin Maghareh, Matthew J. Barnes, Zhuoxiong Sun
In this model, the 9strory benchmark FEM model is remodeled as a 9 degree of freedom shear building model. To evaluate the model the displacement, velocity and acceleration responses of the shear model are compared to those obtained using the FEM model (time history comparison and RMS...

Phenomenological BoucWen Model for 200 kN LargeScale MagnetoRheological Fluid (MR) Damper
27 Jan 2012  Computational Models  Contributor(s): Anthony Friedman, Zhaoshuo Jiang
This is a Phenomological Bouc Wen model for 200 KN largescale magnetorheological fluid damper (a model of the PWM ServoAmplifier used to drive the damper is also included) developed at the Purdue University. The physical counterpart of this model is the 200 kN largescale MR dampers that are...

Modeling of Distributed Realtime Hybrid Simulation
17 Jun 2013  Computational Models  Contributor(s): Amin Maghareh, Ali Irmak Ozdagli
In the last decade, Realtime Hybrid Simulation (RTHS) has become a wellrecognized testing strategy as an alternative to other known testing methodologies such as shake table testing. Essentially, RTHS provides researchers the opportunity to isolate and physically investigate the more...

Direct Simple Shear (DSS) Model
27 Jun 2013  Computational Models  Contributor(s): Arash Khosravifar, Ross W Boulanger, Rachelle Howell, Xiaoyue Wang
This is an OpenSees model of a simple shear test. The model can predict the drained or undrained responses of sand or clay under cyclic or monotonic loading. Two constitutive models are available for the soil, the PressureDependentMultiYield02 (PDMY02) model for sand and the...

15 Aug 2013  Computational Models  Contributor(s): Sarah Hacker, Xin Li, Shirley Dyke
This sample for virtual realtime hybrid simulation (vRTHS) was developed in the Intelligent Infrastructure Systems Laboratory at Purdue University to help users understand the steps necessary to perform a realtime hybrid simulation (RTHS) on a virtual platform. This vRTHS sample uses MATLAB...

A Real Time Hybrid Simulation Demo Code
15 Aug 2013  Computational Models  Contributor(s): Ge(Gaby) Ou, Shirley Dyke
This is an RTHS simulation example including codes ‘RTHS_DM.mdl’ and ‘Trigger_RTHS_DM.m’. In this example, the concept of RTHS and its representation in simulation is discussed. A single story steel structure with predetermined mass, stiffness, damping ratio...
