Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The machine learning-based hybrid seismic analysis developed recently by the authors is validated in this paper using the full-scale experimental data of a shake-table test program performed at the Hyogo Engineering Research Center (E-Defense) of Miki, Japan. The experimental datasets contain the time history responses of two base-isolated buildings, each with the lead rubber bearings (LRB) and the triple pendulum bearings (TPB). First, the machine learning models (MLMs) based on the recurrent neural network (RNN) are designed to predict the complex load-deformation relationship of seismic isolators at the isolation layer. The experimental data are used to train and test the surrogate MLMs. Then, the developed MLMs are incorporated into the time integration method to perform the hybrid seismic analyses of base-isolated buildings subjected to the earthquake ground motions. The hysteresis curves of the isolation layer and the roof displacement time-histories are calculated and compared with the experimental records. The hybrid seismic analysis could capture the experimental responses. The proposed hybrid seismic analysis that takes advantage of both analytical methods and machine learning-based methods was found to be capable of obtaining with good accuracy responses of seismically isolated buildings.
