The acceleration response, strain response, and crack distribution of double-arch tunnels under different intensities and different
You are limited to using only the following materials in your actual structure: 10 Pieces of Spaghetti, 20 Marshmallows, and 30 centimeters of Tape. Your building will be considered “earthquake proof” if it can retain its complete structure on the shake table and not fall over during a period of 10 seconds of shaking the table.
Mar 10, 2016· For almost half a decade, engineers have come to the Pacific Earthquake Engineering Research (PEER) Center to better understand how structures respond to the complex and destructive forces of an earthquake.

Sep 12, 2016· In the event of an earthquake, follow these tips from National Geographic’s website on what to do in an emergency: Drop down; take cover under a desk or table and hold on. Stay indoors until the shaking stops and you’re sure it’s safe to exit. Stay away from bookcases or furniture that can fall on you. Stay away from windows.
Jan 20, 2011· The earliest known shaking table, driven by hand‐power, was constructed in Japan at the end of the 19th century. At the beginning of the 20th century developments had moved to the Stanford University in the U.S. with the introduction of an electric motor to produce a more refined oscillatory motion in one direction, the response of the
Nov 01, 2010· The experiments were performed on a shaking table array consisting of two six-degree-of-freedom shake tables, named as dual multi-axis shake table system (DMSTS). The two shake tables are set on a common rail system with one table fixed and the other table movable, which is referred hereafter as Table A and Table B, respectively (see Fig. 1 ).

The shaking people feel during an earthquake is caused by the energy released when movement is caused by a rupture in the Earth's crust or uppermost mantle. If you compare an earthquake to snapping your fingers, the rupture is the fingers snapping, but what you hear, or "feel" is the sound waves travelling through the atmosphere.
Most earthquake-related injuries and deaths are caused by falling or flying objects (e.g., TVs, lamps, glass, bookcases), or by being knocked to the ground. You can take other actions, even while an earthquake is happening, that will reduce your chances of being hurt.
