Name ___________________________ Date ___________________ Period _______ Design Brief: Earthquake-Safe Building Design Challenge Background: Earthquakes are just one reminder that Earth’s tectonic plates are constantly moving. The shaking can cause buildings to collapse resulting in the loss of possessions, loss of places where people live and work, and even the loss of life. How can humans be proactive in protecting ourselves from the effects of an earthquake? Challenge: The San Francisco Art Society wants to build a brand-new youth art center for the city. You are a world-renowned architect, and the art society wants to hire YOU to build the youth art center! However, you have never been faced with the challenge of building a structure in such a seismically active area. You will need to research techniques used to build an earthquake-safe structure, design and build a model of the youth center, and put your model to the test in a simulated earthquake! Since the building will be used for art classes, you may be as creative as you like with the shape and design of the building (it does not need to be box shaped). Will your design hold up against the seriously seismic P-waves, S-waves, and surface waves? Criteria (requirements): An innovative design must: have 2-4 stories be at least 30 cm tall each story must have a floor & the building must have a roof contain a base isolation system base isolation must be 1-4 cm thick anchoring straps must be able to crisscross over the foundation to keep the building attached to the shake table (test using 2 rulers during construction) Materials 1 bag of mini-marshmallows (10.5 ounces) 500 toothpicks (2 boxes – 250 in each box) 1 meter of string 1 meter of masking tape 20 index cards 1 sponge Constraints (limits): Base foundation must be no larger than the size of a piece of paper. You must be able to see the infrastructure of the building, only two of the four walls may be closed (ie. shear walls) Construction will take place IN-CLASS ONLY Construction must be completed within the timeframe provided Tools/Machines (provided by teacher): Rulers Scissors (Measure twice. Cut once!) Shake table with anchoring straps Name ___________________________ Date ___________________ Period _______ Earthquake-Safe Building Design Challenge: Getting to Know the Problem Describe the challenge you are working to solve. Research 1. Use the websites specified on Google site and/or Google Classroom to investigate how buildings are designed to withstand different stresses. 2. Respond to the “Guiding Questions” that follow to direct your research using words and phrases. 3. After completing your research, discuss with your group your findings. Guiding Questions 1. What causes earthquakes? _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ 2.
