Earthquake Basics and Damage
Waves of energy caused by an earthquake are called this.
Seismic waves.
Flexible
What is a building code?
A law or rule that is created by a community to tell people how to make safe buildings for that specific area.
What does it mean to see or look for similarities that repeat in data?
What is the primary structural cause for the loss of life from earthquakes?
Building Collapse
What structural component is primarily used for support by creating triangles within a building frame?
Cross Bracing
True or False - A building that is rigid will be more likely able to withstand a strong earthquake.
False. The building should be flexible.
How can patterns help engineers build more earthquake proof buildings?
Answer may vary!
They can test buildings and see what patterns show up.
Besides buildings collapsing, name two other ways earthquakes cause damage.
Liquefaction of the ground and landslides/rockfalls.
What material property allows a structure to bend and absorb seismic energy without immediately failing?
Ductility
What does the word mitigate mean when describing building codes to make buildings earthquake proof?
Mitigate means to reduce damage caused by an earthquake (so to make buildings safe).
What is the first step in the engineer and design process?
Determine what the problem is
When the ground suddenly liquifies during an earthquake, this can cause a building to collapse.
These panels of glued wood help to strengthen soft-story buildings in earthquake prone areas.
Cross Laminated Timbers
If a building code says a building should withstand an earthquake, what kind of plate boundary is this building most like near to?
Convergent or Transform plate boundary
True or false - the engineering and design process ends when you are done with each step.
False - you develop new questions to resolve.
We've discussed how liquefaction can make buildings collapse.
How can the analysis of local soil data inform whether or not a building should get earthquake resistant technology so it doesn't fall down during an earthquake?
Analyzing the soil to see how much moisture is present and if it is sandy or not.
What is the name for a specific law that determines how you can build a building in a certain area?
Building code
What is an economic constraint that keeps engineers from using ALL of the technologies for earthquake buildings in every city across the world?
Money or the lack of it.
Why is it important to come up with a consensus of your groups ideas when going through the enginner and design process?
Answers will vary
