Nov 12, 2019 Due to the quasistatic test cannot reflect the seismic records and quasidynamic test cannot reflect the rate-dependent effect, the shake table test is usually considered as the most effective way to reproduce seismic damage on structures 2, 3. The first shake table was built in 1968, and since then, a considerable number of shake table and ... Dec 06, 2018 The shake table test and pseudo-static test give very close results. 17,53 When compared with pseudo-dynamic, both gave similar results on earth pressure coefficients and expected start of failure. 34 The main difference found between testing with a shake table and quasi-static is the stiffness.

Clarks Seismic Lab has equipment for every testing need. Its primary tri-axial seismic shake table is comprised of a 15 x 15 mounting surface (which can be extended up to 26) operating on an independent tri-axial hydraulic system. A comprehensive list of our shake tables and their specs can be found below. When using the shake table, secure it to the table it is resting on using clamps. This will prevent the shake table from walking when the drill is at high RPMs. Expect to pay approximately $100 for a good drill. The rest of the materials should not exceed $25. The aluminum disk may require some machine time and this cost
