  1. Hyperbolic Tangent Model (Version 2) for 200 kN Large-Scale Magneto-Rheological Fluid (MR) Damper

    03 Jun 2012 | Computational Models | Contributor(s): Zhaoshuo Jiang, Richard Christenson

    This is a Hyperbolic Tangent model for 200 KN large-scale magneto-rheological fluid damper (a model of the PWM Servo-Amplifier used to drive the damper is also included) developed at the University of Connecticut. This version (Version 2) added a model of the inductance dynamics of the large-scale …

  2. Evaluation of the 9-Story Benchmark Building Shear Model

    24 Jan 2012 | Computational Models | Contributor(s): Amin Maghareh, Matthew J. Barnes, Zhuoxiong Sun

    In this model, the 9-strory 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 response). …

    28 Jul 2011 | Computational Models | Contributor(s): Shirley Dyke, Juan M Caicedo

    This computational model contains the original files for the Phase I Benchmark Control Problem for Seismic Response of Cable-Stayed Bridges. Dyke, S. J., Caicedo, J. M., Turan, G., Bergman, L. A. and Hague, S. Phase I Benchmark Control Problem for Seismic Response of Cable-Stayed Bridges, Journal …

  4. Hyperbolic Tangent Model for 200 kN Large-Scale Magneto-Rheological Fluid (MR) Damper

    15 Aug 2011 | Computational Models | Contributor(s): Zhaoshuo Jiang, Richard Christenson

    This is a Hyperbolic Tangent model for 200 KN large-scale magneto-rheological fluid damper (a model of the PWM Servo-Amplifier used to drive the damper is also included) developed at the University of Connecticut. The physical counterpart of this model is the 200 kN large-scale MR dampers that …

  5. 9 story building model

    12 Dec 2011 | Computational Models | Contributor(s): Ahmad AlNaseem

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

  6. Phenomenological Bouc-Wen Model for 200 kN Large-Scale Magneto-Rheological Fluid (MR) Damper

    27 Jan 2012 | Computational Models | Contributor(s): Anthony Friedman, Zhaoshuo Jiang

    This is a Phenomological Bouc Wen model for 200 KN large-scale magneto-rheological fluid damper (a model of the PWM Servo-Amplifier used to drive the damper is also included) developed at the Purdue University. The physical counterpart of this model is the 200 kN large-scale MR dampers that are …

  7. Modeling of Distributed Real-time Hybrid Simulation

    17 Jun 2013 | Computational Models | Contributor(s): Amin Maghareh, Ali Irmak Ozdagli

    In the last decade, Real-time Hybrid Simulation (RTHS) has become a well-recognized 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 complicated …

  8. 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 Pressure-Dependent-Multi-Yield02 (PDMY02) model for sand and the …

  9. Virtual RTHS Sample Using xPC

    15 Aug 2013 | Computational Models | Contributor(s): Sarah Hacker, Xin Li, Shirley Dyke

    This sample for virtual real-time hybrid simulation (vRTHS) was developed in the Intelligent Infrastructure Systems Laboratory at Purdue University to help users understand the steps necessary to perform a real-time hybrid simulation (RTHS) on a virtual platform. This vRTHS sample uses MATLAB xPC …

  10. 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 …
