Shaky Table at the Structural and Earthquake Research Center
 
Introduction
The Shaky Table at the Structural and Earthquake Research Center of Amirkabir University of Technology has been designed and implemented using the expertise of internal specialists. The Sharif University of Technology, the Building and Housing Research Center, as well as the Earthquake Engineering and Seismology Research Institute, currently have a shaky table.
Advanced countries such as the United States, Britain, France, Germany, Spain, China and Korea already have shaky table technology. The shaky table of Amirkabir University of Technology is a degree of freedom with a speed of 300 mm / s. The table measures 2.5 x 4 meters and simulates two types of harmonic and earthquake loading. The maximum load this device can handle is 150 kN and the maximum acceleration it can produce is 1.5 times the acceleration of Earth's gravity. On the other hand, the maximum displacement that can be applied to this system is 250 mm. It has two propulsion motors, each capable of generating a speed of 150 mm / s, and the device has the ability to simulate speed or acceleration in single or double motors. To test this device, earthquakes such as El Centro, Kobe and Manjil have been simulated which matched the input waves with very good accuracy.
Simultaneous loads are also modeled with this system and there is a necessary conformity between the input waves and the generated waves. Also, the furrier spectrum of these waves indicates the accuracy required and the desired frequency. This device is capable of measuring and behaving on a variety of structures depending on the weight and wave produced. It should be noted that input Waves can be entered as displacement. It is also possible to confirm the input frequencies according to the furrier wave spectrum. The model is also intended to be placed on a shaky crane table.
Services offered at the center for a variety of experiments include numerical modeling, sample construction, testing, and analysis. The center can collaborate with the applicant at any step of the experiment and facilitate the testing. The system has an accelerometer and the user can determine the acceleration of the system according to the wave entered. Since some earthquake waves require input load modifications, this complex can also assist the applicant.
