32.14.4. IS 13935 Guidelines for Seismic Strengthening

Try these first

1. 1.

   Define retrofitting.

   Hint

   Think about why old buildings might need to be updated.

2. 2.

   What is jacketing?

   Hint

   Recall the techniques discussed in class for local reinforcement.

3. 3.

   What is retrofitting?

   • A method to demolish old buildings
   • The process of strengthening existing structures
   • A type of new construction

   Hint

   Consider why we often upgrade old structures.

4. 4.

   True or False: Energy dissipation devices are used to improve the aesthetics of buildings.

   • True
   • False

   Hint

   What is their primary function during seismic events?

5. 5.

   Consider a three-story building with a history of seismic vulnerability. Propose a comprehensive retrofitting strategy, explaining which methods to use and justifying your choices.

   Hint

   Think about both specific reinforcements and overall structural flexibility.

6. 6.

   Analyze how energy dissipation devices can reduce seismic forces in a high-rise building compared to traditional methods.

   Hint

   Consider the physics behind how energy is transferred during an earthquake.
