Abstract: The analysis of dynamic characteristics and s eismic response of a high_rise control tower of airport with steel frame on the top is given from two respects: model s haking table test and finite element calculation. A 1B 30 scaled model is tested to simulate the earthquake on shaking table. The dynamic characteristics and s eismic res pons e of the prototype structure are got by the s imilar relationship according to the testing results. The dynamic calculations of the model and prototype structures are also made using structural finite element analyses programs and the results are compared and analyzed with the test.
