Answers to questions about old and new buildings, the 2000 standard, seismic resistance grades, and the treatment of buildings that do not meet the standards!
"I want to know the standards for earthquake resistance in housing." This article will answer such questions. Japanese housing has a history of revisions, including old seismic standards, new seismic standards, and the 2000 standards. Additionally, a system has been established to objectively evaluate earthquake resistance through three levels of seismic performance. As major earthquakes are expected to occur in the future, we will clearly explain the system for building homes that can be lived in with peace of mind. *For detailed content of the column, you can view it through the related links.
