What is the most dangerous aspect of an earthquake?
Trees falling
Damage to buildings
Tornadoes that follow an earthquake
How does the large ball suspended at the top of the Taipei 101 skyscraper protect it from earthquakes?
It weighs the building down to make sure it doesn't tip over
It swings in the opposite direction to keep it from falling over.
It rings a large bell to alert people inside to get out.
It alerts an internal system to an incoming earthquake so the foundation can be secured.
The Philippine Arena is the world's largest domed arena. The arena itself is lifted up and isolated from the base by a flexible system of lead rubber bearings (LRB). How do these LRB help to make the building more resistant to earthquake damage?
They create an "invisible cloak" so that energy is rerouted around the building, rather than through the building.
They allow the foundation of the building to move while keeping the rest of the building stable.
They counteract the motion of the building when it sways by moving in the opposite direction.
They increase the weight of the building, which makes it more difficult to move.
The Transamerica Pyramid in San Francisco was built on a steel and concrete base that goes 52 feet underground. This base moves separately from the rest of the building, which allows the rest of the structure to remain stable. Which strategy have the engineers utilized?
Create a Flexible Foundation
Counter Forces with Damping
Shield Buildings from Vibrations
Reinforce the Building's Structure
The Transamerica Pyramid in San Francisco was built with four inner frames extending from the 1st to 17th floors and two more extending to the 45th floor. Which strategy have the engineers utilized?
Create a Flexible Foundation
Counter Forces with Damping
Shield Buildings from Vibrations
Reinforce the Building's Structure
Based on what you see in the picture, which strategy has been used in the "seismic isolated structure"?
Create a Flexible Foundation
Counter Forces with Damping
Shield Buildings from Vibrations
Reinforce the Building's Structure
A building with a steel frame is more earthquake-proof than a building with a concrete frame. This is because...
steel is lighter, stronger, and more flexible than concrete.
steel doesn't bend as easily as concrete.
steel is much heavier and provides more rigid reinforcement.
steel isn't flammable.
During large earthquakes, which is responsible for the greatest number of fatalities?
drowning
fires
people buried alive
Large objects (buildings) fall on people

Engineers have created a model of a building they believe to be earthquake resistant. They are now testing it to validate their claims. What phase of the engineering method are they currently in?
Design
Launch
Development
Concept
What do engineers have to do first before they can move on to the design phase? (choose 3)
Identify the problem
Create a model
Test the model
Set a goal and create a checklist
Brainstorm ideas and look at existing solutions
Match the activity to the correct step of the engineering method.
Identify the issue of building damage during an eartquake
See why some buildings stay standing and others fall
Define requirements of limited damage
Recognize constraints such as time, money, and materials
Create a plan and schedule
Define objectives, what does limited damage mean?
Match the activity to the correct step of the engineering method.
Create drawings and models of the building
Create a prototype of the building
Test the building by running a simulation
Start construction on the building
