Understanding Steel Structures and Seismic Isolation

What is the primary purpose of having several connections in steel structures?

• To make the structure look more complex

• To strengthen and stabilize the structure

• To reduce the cost of construction

• To increase the height of the structure

What is seismic isolation also known as?

• Earthquake proofing

• Base isolation

• Structural reinforcement

• Ground stabilization

Why is it risky for a structure to have only one connection point?

• It makes the structure more expensive

• It increases the risk of failure if that connection fails

• It makes the structure more flexible

• It reduces the aesthetic appeal

What happens to conventional buildings during an earthquake?

• They remain completely stable

• They shake with the earth

• They float above the ground

• They become earthquake-proof

What is the benefit of using base isolators in buildings?

• They make buildings taller

• They allow buildings to move in a slow horizontal motion during earthquakes

• They reduce the cost of construction

• They make buildings more colorful

Which city is mentioned as commonly experiencing earthquakes?

• New York

• San Francisco

• Chicago

• Miami

What is the main disadvantage of using base isolators in construction?

• They are less effective than traditional methods

• They increase the cost of construction

• They make buildings less stable

• They are illegal in some areas

What is the primary advantage of seismic isolation for buildings?

• It makes buildings more energy-efficient

• It reduces the shaking during earthquakes

• It increases the number of floors a building can have

• It makes buildings more attractive

What is the main reason builders in earthquake-prone areas use base isolators?

• To save money

• To enhance the building's appearance

• To increase safety during earthquakes

• To reduce the building's weight

What is the effect of a building being constructed with its foundation laid directly into the ground during an earthquake?

• The building will float

• The building will shake with the earth

• The building will become earthquake-proof

• The building will not be affected
