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-Nara Womans University-HiroshimaUniv.-OitaUniv-KumamotoUniv..

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 part of a joint research project with the Kyoto University Research Institute for Sustainable Humanosphere, this year we successfully assimilated data for three- and five-story wooden buildings, publishing these as peer-reviewed papers 1 and 2. We also applied this data to a new damage prediction method, obtaining favorable results, which we published as peer-reviewed paper 3.
The peer-reviewed paper published in 2023 won the 2024 Quality Engineering Award, Silver Paper Award.
