The current seismic code is based on calculating the earthquake hazard of the building’s location on an address-specific basis. This approach aims for the design to match ground conditions more accurately.
Main Changes
- Use of address-specific earthquake hazard maps
- Different design classes by building height
- A greater weight of the soil survey in design
- Stricter detailing rules
When applied correctly, the new rules markedly improve the seismic performance of buildings. That is why supervising execution on site is as critical as the design itself.
