What is Retrofitting?
Retrofitting is the method of modifying or repairing something after it has been manufactured. Retrofitting work includes changing or repairing the structure system of a building after its construction and occupation. This work result in increased safety and durability of the structure. Retrofitting of buildings is required for homes that are affected by failures and damage by seismic forces. Retrofitting done for your home makes it resistant to seismic activity caused by earthquakes.
What Is The Need Retrofitting?
There are several problems that structural members experience and needed to be tackled among them some common problems include:
- Structural cracks
- Damage to structural members
- Excessive loading
- Errors in design or construction
- Modification of the structural system
- Seismic damage
- Corrosion due to penetration- honeycombs
Methods of Retrofitting
Adding New Shear Wall ● Adding Steel Bracing ● Wall Thickening Technique ● Base Isolation Technique ● Mass Reduction Technique ● Jacketing Method ● Fiber Reinforced Polymer (FRP) ● Epoxy Injection Method ● External Plate Bonding
●Energy Efficient ● Increases Lifespan ● Existing Building can be made Green Later on ● Allow changes in future as per need ● Lower carbon emissions from building activities ● Upgrades existing elements of a building ● Adaptation of new technologies ● Materials from a structure can be reused in come cases ● Reduce maintenance cost
