Shake table is the most effective and well-organized device than any other test for understanding the basic concepts of earthquake. This paper provides a well-organized, effective, economical, and affordable single-DOF shake table. It gives a straightforward and user-friendly platform for engineering students to practically understand and carry out the scientific study of earthquakes. The study proceeds with the proper designing and erection of a single DOF shake table with a payload of 30 kg and a frequency of 0–25 Hz. Steady-state analysis of an identical structure made of steel and aluminum is done in SAP2000, conventional shake table and designed shake table, and results are compared. Harmonic analysis (sinusoidal wave) of three structures with different height is carried out in SAP2000 in order to study the impact of their height on the seismic response of structure. Harmonic sinusoidal wave applied on the above structures in SAP2000 is obtained from the designed shake table. Data translation system and QuickDaq software are used for recording the harmonic data. The single-DOF shake table assembled with an economical cost of INR 50,000 only proved effective for seismic analysis of structures at the academic level. It is also seen that as the height of the structure increases, the displacement of structure increases, and the base shear decreases.
