How did the seismic standards change in the 2025 Building Standards Act amendment?

Due to the increased weight from energy-efficient housing, the required wall quantity has been revised to increase by an average of 1.41 times from the old standards.

Is the current 'Seismic Rating 3' still safe under the new standards?

Yes. Simulation results have confirmed that buildings with Seismic Rating 3 will not collapse even in earthquakes of the Kumamoto class.

What is 'wallstat' used for verification?

It is software that can analyze the damage and collapse process of wooden houses during major earthquakes by inputting the building's structure and seismic wave data.
