2D Unit Cell Model of Prefabricated Drain in Liquefiable Soil

16 Jan 2014 | Computational Models | Contributor(s): Rachelle Howell, Xiaoyue Wang, Ellen M. Rathje

This OpenSees model is a 2D plane strain model of the area of influence around a single drain (or, in the case of the untreated model, a free-field untreated area equal to the area of influence around a single drain). It was developed to simulate lateral spreading in the SSK01 and RNK01...

3-D Longitudinal Performance of Rehabilitated Sewer Pipelines Based on Experiments of Actual Pipes and Finite Elements Analysis

26 Mar 2013 | Publications | Contributor(s): Danesh Nourzadeh, Shiro Takada

Reinforced concrete cylindrical pipes (RCCPs) are one of the most widely used sewer conduits all over the world. These pipelines are very vulnerable to the corrosion and accident due to traffic loads, and other hazards such as earthquakes. One of the methods for rehabilitation of these old...

3-Pier Hybrid Simulation Using Zeus-NL and Matlab

30 Jul 2011 | Poster | Contributor(s): Patricia Joan AuBuchon

Hybrid Simulations can allow for more accurate and controllable testing by using strong computational data and experimental data while testing.The University of Illinois at Urbana-Champaign (UIUC) will be employing such techniques to study spiral reinforced concrete columns. The NEES@UIUC...

3D Data Viewer Tutorial Video

12 Jul 2011 | Poster | Contributor(s): NEES EOT

By incorporating the visualization of 3‐D data in the Real‐Time Data Viewer (RDV), researchers are presented with a whole new world of visual data to explore. At the MAST Research Lab at the University of Minnesota, streaming live three dimensional data from a Metris K600 Optical Coordinate...

3D Unit Cell Model of Prefabricated Drain in Liquefiable Soil

29 Jul 2014 | Computational Models | Contributor(s): Rachelle Howell, Xiaoyue Wang, Ellen M. Rathje

This OpenSees model is a 3D unit cell infinite slope model of the area of influence around a single drain (or, in the case of the untreated model, a free-field untreated area equal to the area of influence around a single drain). It was developed to simulate lateral spreading in the in-plane...
