Push and pull the Slinky at the same time that you move it up and down; your hand should move in a circle. This circularmotion wave models an earthquake wave called a Rayleigh wave. Rayleigh waves transmit energy from the epicenter the point on the surface that's above the focus .

• Connect the toothpicks and marshmallows to build your design. • You do not need to use all of the marshmallows, but you cannot use any more than 30. Test the structures. • Place the structure on the testing platform. • Start with a gentle earthquake. Use your finger to gently shake the platform. Observe how the structure moves.

Some will stand anything, some will fail with the slightest shaking. How far is the earthquake? How deep is the origin? What caused the earthquake? ... What was it like to survive an earthquake that took down the building you were in? Niven A. Nolte. Answered Jul 11, 2018 · .

So far, we have developed MINDSTORMS EV3 code for a random earthquake simulator and for one that starts slow and ramps up to top speed. Building the shake table itself is an exercise in using gear trains, translating rotational motion into linear motion, and combining power sources to run the same gears.

Seismic Design Categories. The NEHRP Recommended Seismic Provisions. recognizes that, independent of the quality of their design and construction, not all buildings pose the same seismic risk. Factors that affect a structure's seismic risk include: • The intensity of ground shaking and other earthquake effects the structure

Earthquakeresistant Building Materials for Your Home An earthquake can devastate your life and your home, so if you live in an area which is prone to tremors, it may be worthwhile to utilize some earthquakeresistant building materials to minimize damage .

buildings to crumble. Engineers continually strive to make buildings stronger to resist the forces of earthquakes. Engineers face the challenge of designing more robust buildings to withstand earthquakes. Earthquakeproof buildings will bend and sway with the motion of an earthquake, instead of cracking and breaking under the pressure.

The engineers do not attempt to make earthquakeproof buildings that will not get damaged even during the rare but strong earthquake; such buildings will be too robust and also too expensive. Instead, the engineering intention is to make buildings earthquakeresistant; such buildings resist the effects of ground shaking, although they may get damaged severely but would not collapse during the strong earthquake.

After you feel an earthquake, is it best to leave a highrise building? ... You cannot outrun an earthquake. When you feel shaking begin, the game is on.
