L To discover how people prepare for earthquakes To build your own earthquake proof building How can we survive earthquakes? Key terms: Shock absorbers, foundations, diagonal bracing, retro-engineering ‘Why this building?’ Watch the clip of the aftermath of the Christchurch earthquake. Can you answer the survivor’s question: ‘Why this building?’ With each engineers about HOW buildings shaking. earthquake, learn more to design to withstand Torre Major, Mexico City This is the Torre Major in Mexico City, Central America. It is said to be the strongest building in the world. Yet it is built in one of the world’s most unstable areas. Q: How is it so strong? Watch the clip and fill in your ‘Engineer’s Factfile’. Clip from ‘10 Things you didn’t know about Earthquakes’ Kobe, Japan In Kobe Japan engineers have built some amazingly strong buildings. Add notes to your pictures. Complete your factfiles! Rubber Shock Absorbers on the Hanshin Expressway absorb the shaking! Retro-engineering involves building a strong exo-skeleton around existing buildings, such as the red girders around Kobe port tower Quake-proof designs Extra beams and reinforced steel girders! Buildings with wide bases!! Diagonal cross bracing Spaghetti and Marshmallow Earthquake Proof Buildings • Design, build, and test a model structure made out of uncooked spaghetti sticks and marshmallows! • Your model will be tested on CRAP’s stateof-the-art earthquake simulator machine: "The Shake Table." • Your model should be able to withstand a 10 second earthquake without collapsing. • You will be competing against other teams by attempting to build the best structure. • You and your team mates will give a brief presentation prior to the final test.
