| 英文摘要 |
This work proposes a framework of a new method to run a hybrid simulation, which is named online updating hybrid simulation. An online updating hybrid simulation is a hybrid simulation in which numerical model parameters of its numerical substructure(s) are adjustable and instantly updated based on the instantaneously-measured responses of experimental substructures. This work is a collaborative work between the National Center for Research on Earthquake Engineering(NCREE) and the Mid-America Earthquake(MAE) Center, which is located at University of Illinois at Urbana Champaign, USA. The MAE Center group plans to develop the near term neural network-based approach to updating the response of the repetitive analytical components in hybrid simulation(e.g., beam-column connections) based on the instantaneously-measured response of the experimental component. NCREE is planning on developing algorithms for the updating of material models used in finite element analysis using measured data, during the same test. This report is a four-page shortened version of a progress report of the first year work on online updating hybrid simulation. Figures in this report are resized. Full-size figures can be found at NCREE report 09-001 [1]. Most of the research work written in this report was completed during the first author’s one-month short visit at the MAE Center under supervision and discussion of the third author of this report. Further details of the upcoming work will be described in the near future. |
