Abstract

JAXA and Kyoto University are researching with quality engineering tools (JIANT) and wallstat, a seismic simulator for wooden buildings.

Our theme is research on the combination of testing and simulation (data assimilation).This study is a joint research of JAXA-Kyoto University-Osaka Institute of Techinology.

Reasons and benefits of using JAXA Supercomputer System

The purpose of using a supercomputer is to speed up calculations.

The calculation of wallstat takes 40 minutes per case on a general PC.

That means that if we perform 6000 calculations in one case study, it takes a total of 160 days, but if we use JSS3, we can complete them in a few hours.

Achievements of the Year

As a research with Kyoto University Research Institute for Humanosphere, we studied data assimilation under multiple design targets/environmental conditions this year (Fig1). This time, we focused on a three-story building and adjusted it for two buildings and two seismic waves. A summary of the results achieved so far was presented in a special lecture at the 31st Society for Quality Engineering Technology Presentation in June 2023. At this competition, he received the 2023 Quality Engineering Society Japanese Standards Association Chairman’s Award.
