The design methods in shaking table test design are given as follows [6]: Firstly, three controlling scaling factors needs to be determined. That is the scaling factor of length, stress, and acceleration. Considering the size of shaking table and the crane walking height, the length scaling factor is
Keywords: Earthquake simulator, shaking table, SDOF, Labview I. Introduction: Earthquake or seismic analysis is a subset of structural analysis which involves the calculation of the response of a structure subjected to seismic excitation. This is required for carrying out the structural design and structural

Design of the prototype structure. Design of the shake-table test structure. Selection and scaling of ground motions
The use of shaking tables for the assessment of the dynamic and seismic behaviour of civil engineering structures is effective since the sixties. At the beginning, shaking tables had important limitations concerning the power available and they have been used to study the dynamic characteristics (natural frequencies and mode

For the particular case of the UPRM haking table the maximum design payload s capacity of the shaking table will depend on three factors [5]: 1. Desired maximum base acceleration, A max 2. The force that can be applied by the actuator, F max 3. The load bearing capacity of the Linear Bearing System The maximum weight of the test structure plus

SHAKING TABLE TESTS AND RESULTS Similitude Design of Models The reliability of model tests depends on whether the model can represent the real behavior of the prototype system. In the shaking table model test on SSI, similitude law should also be taken into account. However, only similitude design of superstructure and foundation is generally

These factors should be focused on to meet the similitude ratio design of the dynamics of landslide in Shaking table test design. Based on study of dynamic similitude law of landslide, the method of changing model soil specifications is used to prepare the model soil which is in accordance with the maximum shear modulus of prototype soil
