Earthquake Proof Structures

How have humans learned to live and survive in areas where natural hazards occur?

• They have adapted buildings and structures to withstand the hazard.

• They have put up large walls to keep the hazard out.

• They use more renewable energy to reduce how severe the hazards are.

• They don't really care and just live there anyway.

What role do shear walls play in earthquake-resistant structures?

• They provide aesthetic appeal

• They help in reducing the building's weight

• They resist lateral forces during an earthquake

• It determines the building's color scheme

• It affects how the building will sway during an earthquake

• It is used to calculate the building's cost

• It is irrelevant to earthquake engineering
