Earthquake Questions
How are earthquake proof buildings constructed and how do they work? What are the advantages of them and how do we work through the disadvantages?
Thank You

Most of them have a counter-weight located somewhere in the structure. This is a large object with a very high mass that is allowed to swing freely, so effectively a large pendulum. When an earthquake shakes the ground the counter weight swings in the opposite direction and counter balances the building. The buildings structures are built specifically to withstand the tension of being pulled different ways.
Advantages: Saves lives as buildings with counter weight don’t usually fall down.
Disadvantages: Much more expensive, with not only the weight but the structure and extra construction fees.

They are constructed with rubber and steel. They are seismic buildings and the rubber absorbs the shock of the earthquake.
They have advantages
Such as
- Better stability
They have disadvantages
Such as
- Expensive
