How structural retrofitting strengthens existing buildings to meet modern safety standards.
Retrofitting is the process of strengthening an existing building so it can safely carry current loads and resist earthquakes. It extends the life of a structure without full reconstruction.
Why retrofit?
Many older buildings were designed to outdated standards or have deteriorated over time. Retrofitting brings them up to modern safety levels.
Common retrofitting techniques
- Concrete or steel jacketing of columns and beams
- Adding shear walls or bracing
- Foundation strengthening
- Fibre-reinforced polymer (FRP) wrapping
