in this research, quake resistance of a high-rise building is verified through the shake table experiments conducted by e-defense. the most likely height of high-rise buildings is considered to be about 80 m in japan. the test specimen is designed to represent seismic responses of a 80 m tall steel building.
in order to acquire realistic data on the damage, a series of shaking table tests on a high-rise building is conducted by using 3-dimension full-scale testing facility, nicknamed 'e-defense' [1-3]. the adopted test system consists of a lower part represented by four-story steel moment frame structure and an
a shaking table test of largea -scale model with liquefiable sand deposit was performed at the e-defense shaking table testing facility. the model in a rigid container 16 meters long, 4 meters wide and 5 meters high had a pile-foundation structure behind caissontype - quay wall in the deposit.
shaking table-test model coupled dynamics in e-defensesimulation using linear medel. the national research institute for earth science and disaster prevention (nied) is now conducting for constructing a three-dimensional full-scale earthquake testing facility (e-defense).this facility has 24 actuators to supply enough power to the shaking table
the result is the e-defense (“e” stands for earth) shake table, measuring 20 by 15 meters, the world’s largest earthquake simulator, located about 30km north of kobe. the simulator is a basically a kinetic platform with 24 pneumatic pistons attached to the
moment resisting frame steel structure manufactured and tested at japan's e-defense testing facility. a series of shake table experiments were conducted in 2007 to excite the structure with scaled records of the 1995 kobe earthquake. the structure was densely instrumented with accelerometers, strain gauges, and laser transducers, which collected adequate data for full characterization of the response history

21/12/2008 blind analysis results was announced. 12/10/2007 updated a movie page. 02/10/2007 finished live webcast of full-scale shaking table test. 20/09/2007 live webcast of full-scale shaking table test. 03/08/2007 deadline for registration of 2007 blind analysis was. postponed till aug. 15.
a shaking table test was conducted at the e-defense shaking table facility to investigate the damage and collapse behavior of a steel high-rise building under exceedingly large ground motions. the specimen is a one-third scale 18-story steel moment
an assessment of a four storey prestressed reinforced concrete structure is compared to existing results for a full scale shake table test. the e-defense structure, which was tested in 2010 and was subjected to the kobe earthquake record, is a complex concrete structure with prestressed rocking shear walls in one direction and a moment frame in the other.
shaking table by the mitsubishi heavy industry co. e-defense is the very large scale and high performance testing facility in the world. therefore, many researchers, which are belonging not only japanese but also worldwide organizations, can use this facility for their researches. e-defense should be operated the international common use.
shaking table experiment of a hospital building was conducted at the e-defense facility. a specimen consisted of fixed-based and base-isolated structures, connected by a walkway with an expansion joint, were shaken together for the first time in the world. the specimen was equipped with nonstructural components and medical equipment
cryospheric snowfall, drift and avalanche simulator at e-defense. nied also features a smaller shake table in addition to a rainfall simulator and a cyrospheric environment simulator. the last of these is designed to study snow disasters (including avalanches, often caused by quakes) using a snow-making machine and wind tunnel system.
there are several different experimental techniques that can be used to test the response of structures and soil or rock slopes to verify their seismic performance, one of which is the use of an earthquake shaking table (a shaking table, or simply shake table ). this is a device for shaking scaled slopes, structural models or building components
friday, april 11, 2014. the largest shake table experiment ever conducted shook this full-size seven-story condominium built at the japanese national research institute for earth science and disaster prevention's earth-defense facility ('e-defense') in 2009. credit: john van de lindt. on a muggy day in mid-july 2009, a lone seven-story
evaluation of simplified and state-of-the-art analysis procedures for steel frame buildings equipped with supplemental damping devices based on e-defense full-scale shake table tests
this paper presents key parameters that affect numerical modeling of steel frame structures for reliable collapse simulations. the collapse assessment is based on experimental data obtained from a full-scale shaking table collapse test of a 4-story steel moment frame and a blind numerical analysis contest that was organized in parallel with the collapse test.
e-defense shake table the earthquake engineering research institute (eeri) is a leader in dissemination of earthquake engineering research related information both in the u.s. and globally. a definitive list of earthquake engineering research related shaking tables around the world may be found in experimental facilities for earthquake engineering simulation worldwide. 
higher pore pressure in this region in test tb02 agrees with the observation of larger damage of anchor in this test. figure 8 shows tie rod forces in test tb02 and tb03. it can be seen that in test tb02 tie rod force decreased after the base motion was applied. whereas in test tb03 the trend was reverse and tie rod has increased.
so, as i said earlier, the table tennis grip is important because it controls the angle of the racket, which in turn controls the height of the ball, the depth of the ball, the speed of the ball, the direction of the ball, the type of spin and the amount of spin. here's a video demonstration of the shake-hands table tennis grip.

target areas may be regarded as a notional 18 inches square. they need not be marked out in full. a, b, c, d are the centre points of the four courts. two sheets of a4 paper can form a useful approximation of these centre areas when rehearsing the tests. so, i recommend that you use the above skill tests to improve your table tennis skill level.
