Verification of Damage Prediction Method for Wooden Frame Houses Using Data Assimilation Method Based on Quality Engineering

Abstract

The objective of this study was to quantitatively evaluate the extent of damage to the structure of a wooden house when it is damaged by an earthquake. The accuracy of the simulation model was improved and the prediction accuracy was verified by using a data assimilation method based on quality engineering. The data assimilation was performed by using the results of small and medium excitation tests, respectively, and by performing a comprehensive simulation that considers the effects of material variation, construction error variation, and the safety factor. The data assimilation method, including parameter settings, was verified by comparing the response results of medium and large excitation using the model after data assimilation.
