The 1994 magnitude 6.7 earthquake in Northridge, Calif., and 1995 magnitude 6.9 earthquake in Kobe, Japan, clearly demonstrate the seismic vulnerability

Shaking Table Test of a RC Box Shear Wall under Uni-directional Input Motion Kazutaka Shirai 1) , Hideo Katsumata, Kazuaki Tsuda1), Matsutaro Seki 1) Technical Research Institute, Obayashi Corporation, Tokyo, Japan ABSTRACT Shaking table tests of RC box shear walls subjected to uni- or multi-directional input motions have been

Jan 01, 2011 A series of full-scale tests was conducted on the E-Defense shaking table facilities in Japan to simulate various levels of realistic seismic damage in a high-rise structural steel building. During the shaking table tests, the specimen experienced damage of the concrete slabs, beam-to-column connections, and nonstructural walls

Before the shaking table test, static stability of reinforced soil wall with saturated backfill was investigated by raising the water level under the centrifugal gravity. As a result, the wall showed sufficient stability statically

The shaking table tests were carried out at the shaking table of Chiba Experiment Station in Institute of Industrial Science. Horizontal unidirectional shaking was conducted. Figure 3 shows the experimental method. The vertical load of 39.9kN made of

Shaking table test and numerical simulation of seismic response of subway structures A. Che and T. Iwatate Department of Civil Engineering, Tokyo Metropolitan [email protected], Tokyo, Japan. Abstract In order to clarify the dynamic behaviors and damage mechanism of subway structures due to the 1995 Hyogoken-nanbu earthquake, scaled model shaking

Seismic retrofit and shaking table test of medical equipment in a hospital J.-F. Chai & F.-R. Lin National Center for Research on Earthquake Engineering, Taipei, Taiwan ABSTRACT: Due to the variety in the categorization of nonstructural components and medical equipment in a hospital, before embarking on seismic design, the critical and/or

The shaking table they created is the same one operated by PEER today and is still the largest multidirectional shaking table in the United States and among the most sophisticated in the world. Many of the design features originated in Berkeley, were later adopted for shaking tables in Japan, Mexico, Peru, and Yugoslavia

Disk drive testing. 2075E Vibration Shaker – The most versatile option for shaker table testing. This compact, portable shaker can produce up to 75 lbf, making it suitable for a wide range of applications. The 2075E provides a 3.25 in diameter platform table with (5) 10-32 inserts, making it easy to attach test objects
