Building Techniques for Earthquake Safety

What is the main reason people die in earthquakes according to the video?

• Natural disaster alerts

• Buildings that collapse

• Lack of preparation

• Earthquakes themselves

What are the two building techniques mentioned in the video?

• Base isolation and tuned mass damper

• Wall reinforcement and window protection

• Earthquake alarms and emergency exits

• Foundation strengthening and roof bracing

What did Justin use to test the buildings?

• A shake table

• A wind tunnel

• A water tank

• A model house

Which building technique is often used in tall structures?

• Foundation anchoring

• Tuned mass damper

• Wall shear

• Base isolation

What happens to the building with the tuned mass damper during shaking?

• It becomes heavier

• It sways a lot

• It collapses immediately

• It stays steady and doesn’t wobble

What can affect the outcome of the experiments?

• Type of shake table used

• Time of day

• Height of the tuned mass damper and building

• Color of the buildings

What is base isolation?

• Adding more floors to a building

• Strengthening the foundation

• Lifting the building off the ground with shock absorbers

• Building a taller structure

What did Justin say helps minimize the movement of the building?

• Strong materials

• Water-filled containers

• Swinging plates

• Heavy walls

Which technique is better for houses according to the video?

• Tuned mass damper

• Steel frames

• Base isolation

• Concrete walls

Who provided tips and advice for making the base isolation unit?

• A school teacher

• Larry Bullis at Straddling Pendulum Limited

• A family member

• A construction worker
