Earthquake-Proof The Buildings that Could by Nicholas Busque 260429206

Effects of Earthquakes: ● Quick Facts: Leading cause of death during earthquakes- civil structure collapse ○ Major losses in buildings ○ catastrophic events (tsunamis) ○ Major financial costs (billions $$) ○

Burj Khalifa The Tallest, The Strongest. .

Burj Khalifa source: http: //did-you-know-thats. blogspot. ca/2013/05/burj-khalifa. html

Quick Facts: ● About 2, 720 ft tall or approximately 661 m tall ● Tallest building in the world ● In Dubai, United Arab Emirates ● Experienced earthquake in 2008 (during construction) ● Experienced remnants of another earthquake in 2010 (resonating frequency!) ● 192 supporting piles (50 m deep into the ground) ● 1. 5 Billion dollars to build

Strengths of Khalifa: Torsionally-rigid Foundation-rigid Supporting Structure -rigid Strong mean machine

Yokohoma Landmark Tower Japan’s poke at the sky.

Quick Facts: ● 296 m tall or 971 feet ● Tallest building in Japan, 3 rd tallest structure ● built 1993, in Yokohama City Yokohama

Special Design Qualities: ● Rollers at base ● Flexible structural Materials ● HMD’s ● http: //www. archdaily. com/11918 1/seismic-architecture-learningfrom-the-japan-experience/

Neat Visual Comparison:

Torre Mayor Beast of Mexico City

Quick Facts: ● 57 stories ● Finished in 2003 ● Experienced 7. 6 magnitude shake ● Makes use of Cold War technology

Fluid Viscous Dampers: ● Originally used during Cold War ● Added support against shock from nuclear detonation ● Two sizes implemented in Torre Mayor ● Same concept as hydraulic/suspension on vehicles, doors, etc. .
