structural dynamics and earthquake engineering; topics which are rarely introduced at the undergraduate level. The primary vehicle for introducing these topics is a small-scale bench-top shaking table. Furthermore, the lab will introduce the concept of base isolation and explain how an isolation system affects the dynamic behavior of a structure

Shake tables. The Center has three biaxial shake tables in operation. Manufactured by MTS, each table measures 14 x 14.6 ft (4.3 x 4.5 m), has a stroke of 12 in ( 300 mm), and can reach a peak velocity of 40 in/sec (1000 mm/sec) and an acceleration of 1g with a 50 ton payload (445 kN). All three tables can be constrained to act together as a single large table, or they can be operated individually with

LNEC’s current 3D shake table was designed specifically for testing civil engineering structures and components up to collapse or ultimate limit states. A special feature is its capacity in terms of payload (specimen weight 40 t), allowing testing of small real scale buildings (1-storey, 3D concrete frames have been tested) or larger

Compression Test on Bricks – This test is conducted to determine the compressive strength of the brick. The crushing strength of the brick should not be less than 3.5 N/Sqmm. Water absorption test – The bricks should not absorb more than 20% of water when immersed in water. It is calculated by the ratio between the dry weight of the brick to the weight of the saturated brick

Shaking table model tests on soil-structure interaction system in liquefiable ground are described in this paper. A flexible container was fabricated to minimize the box effect. Pile foundation was used in the test. A 12-story cast-in-place R.C. frame model was used as superstructure, and sand soil was employed as model soil. In the

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

The College of Civil Engineering of Tongji University houses two 70-ton shake tables and two 30-ton shake tables within their Multi-Functional Shaking Tables (MFST) Lab. The tables can be arranged in multiple configurations anywhere within two adjacent trenches enabling researchers to test longer and larger test specimens
