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-Nara Women’s University.

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
The test results of a two-story wooden building and the simulation were combined. Originally, the cycle and maximum value of the results did not match, but by performing a comprehensive calculation of 14641 cases, we obtained almost the same results. The calculation time in JSS3 was about 3 hours.
Since good results were obtained, we made presentations to the Architectural Institute of Japan, the Wood Society, etc.
