Abstract：A series of earthquake simulation tests were carried out on the shaking table with different waves and different earthquake levels for 1/40 model of a super high steel TV tower. The dynamic properties, seismic responses, damping ratios and the variations of the natural frequency under different wave peak were studied. The seismic responses of the prototype structure were studied based on the similitude theory. With the data achieved in the test, the first three frequencies of the structure are 0.303Hz (translation in direction X), 0.317Hz (translation in direction Y), and 0.625Hz (torsion), corresponding periods are 3.3s, 3.15s and 1.6s. The ratio of period of the torsion to that in two horizontal directions are 0.48 and 0.51, the maximum inter-story drift under frequently occurred earthquake and seldom occurred earthquake are 1/807 and 1/99, all of this indicate that the structure have a good earthquake-resistant behavior, and can satisfy the requirement of the building code.
