One of the main activities of this RCN will be workshops. Stay tuned for further information.

Machine Learning in Hybrid Simulation 

The goal of this workshop was to discuss the potential for machine learning to enhance our ability to perform better or accelerate hybrid simulations, as well as our ability to learn from the results of hybrid simulation. The workshop consisted of four short informal vision talks, followed by small group discussions to generate new research ideas. Presentations to trigger the discussion were:

  1. James Ricles, Lehigh University, Multi-Natural Hazards Performance Assessment of Soil-Foundations Structural Systems using Realti6me Hybrid Simulation and Machine Learning-Trained Neural Networks.
  2. Jin-Song Pei, University of Oklahoma, Interpretable Machine Learning for Nonlinear Static Function Approximation.
  3. Ali Imanpour, University of Alberta, Edmonton, Multi-element Seismic Hybrid Simulation Combining Hysteresis Modeling and Recursive Model Updating.
  4. Mao Cheng, University of California, Berkeley, Model updating using LSTM for initial selection.

3rd Workshop (Virtual) - Jointly held by UniValle and MECHS: "Confronting New Challenges"

The 3rd Joint UniValle/MECHS Workshop was held July 15-16 virtually. The Universidad del Valle (UniValle) from Cali, Colombia participated directly in organizing this workship in which a group of researchers participated including multi-hazard engineering researchers, graduate students, international partners, practitioners, and interdisciplinary collaborators. During this 2 day virtual workshop we aimed to focus on two specific topics: a) nonlinearities and managing uncertainty, and b) computational bottlenecks. Two 20 minute presentations were delivered each day to jump start the conversation, followed by a discussion intended to identify the requirements to overcome current challenges in these techniques.

2nd Workshop - Jointly held by ETH and MECHS: "New Frontiers and Innovative Methods for Hybrid Simulation"

The 2nd MECHS Workshop (held in partnership with ETH-Zurich) was held March 13-15, 2019 in Zurich, Switzerland. A group of 35 researchers participated including multi-hazard engineering researchers, graduate students, international partners, practitioners, and interdisciplinary collaborators. Resilient infrastructure requires that we strive to obtain a deeper understanding of the salient behaviors and uncertanties present when structures are exposed to hazardous loading conditions. When structural systems are too large or complex to test in the laboratory, the cyber-physical testing method known as hybrid simulation (HS), a.k.a. dynamic virtualization, provides an important tool for their examination. Presentations were given by participants and are provided on the HySim19 website.

1st MECHS Workshop: "Breaking Barriers and Building Capacity"

The 1st MECHS Workshop was held December 12-13, 2017 in San Diego, California. A group of 40 researchers participated including multihazard engineering researchers, graduate students, international partners, and interdisciplinary collaborators. During this 1.5 day workshop we aimed to:

  • Bring together a diverse group of researchers to discuss challenges and the opportunities enabled by establishing the next generation of Hybrid Simulation and Real-time Hybrid Simulation methods;
  • Engage researchers that may be new to Hybrid Simulation, while leveraging the expertise of researchers working in Hybrid Simulation;
  • Identify directions that will break through barriers that have hindered past applications of these methods;
  • Build Capacity to enable Hybrid Simulation at more laboratories; and
  • Develop a Research Agenda for Hybrid Simulation

Short presentations were given by participants and are provided ( short presentations ).

The community vision for hybrid simulation has evolved over the last several years. A task group was formed within the NEES Simulation Steering Subcommittee, and based on the results of a community survey, was charged with tasks to develop materials of use to the community. Two task group meetings were held in 2014, one on developing a primer and common vocabulary for hybrid simulation, and the second on discussing the assessment criteria. The documents resulting from those discussions are available on the Resources page.

Several conference sessions on HS and RTHS have been held to promote this method, and to share and discuss solutions to the main challenges:

  • EMI 2018 Engineering Mechanics Institute Conference, Cambridge MA, May-June
  • EMI 2017 Engineering Mechanics Institute Conference, San Diego, June.
  • 7AESE 2017 7th Advances in Experimental Structural Engineering, Pavia, Italy, September.
