A shake table is a dynamic earthquake simulator that can “re-play” the record of earthquake motions from a past earthquake or vibrate to represent expected future ground motions. The largest such facility, able to carry a structure weighing 1200 metric tons, is located in Miki City, Japan and is known as E-Defense. The shaking platform is
This project subjected three one-third scale single columns to Sylmar earthquake with gradually increasing PGA using one of the shake tables at the University of Nevada, Reno and the mass-rig setup. After each test, the column was repaired rapidly, using CFRP wrapping, and retested to evaluate the emergency repair performance.
The shaking table runs using a hydraulic linear actuator with a maximum static force of 250 kN. The actuator has a maximum stroke of +/- 25.4 mm. The simulator is controlled using advanced seismic simulation software that uses non-linear multi-pass on-line …

Earthquake Tip. Learning Earthquake Design and Construction. What Causes Earthquakes? The Earth and its Interior Long time ago, a large collection of material masses coalesced to form the Earth. Large amount of heat was generated by this fusion, and slowly as the Earth cooled down, the heavier and denser materials sank to the center and the lighter ones rose to the top.

The Mid-America Earthquake Center is a National Science Foundation Center for Earthquake Engineering. Synthetic ground motions distributed with USEE were developed by Y. K. Wen and Chiun-Lin Wu as part of project RR-1 of the Mid-America Earthquake Center (1999). Previous work by Mahin and Lin (1983), which included a
Sep 19, 2014 A series of large-scale shaking table tests were performed to investigate the damage mechanisms of a three-arch type subway station structure in a liquefiable soil experiencing strong motions. Methods to measure the displacement included the vision-based displacement test and the fiber Bragg grating test to measure the strain of the galvanized steel wire.

Feb 13, 2021 A tunnel driven in loess soil in an earthquake-prone area may be subject to a variety of other external actions. Considering the coupling effect of earthquake activity, rainfall seepage and traffic movement, a dynamic model of a two-lane tunnel driven in a loess soil and a model of rain seepage are established. Using near-field pulse earthquake excitation, the influences of tunnel driven in a ...

Dec 13, 2005 The 2004 Indian Ocean Tsunami has given us an opportunity to think about extreme events in natural disasters. Data analyses on disasters in 20 th century revealed that extreme natural disasters as catastrophic as the Tsunami had actually occurred once in every 16 years in Asia. The reason the Tsunami shocked us so much is that normal people did not expect such an extreme event …
