摘要
对顶部两层钢框架的高耸筒体塔台结构在地震作用下的动力特性与反应,从模型振动台试验和有限元计算两方面进行了研究。对一个1∶30比例的机场控制塔台模型进行了振动台模拟地震试验,根据试验结果,通过相似关系得到原型结构在地震作用下的动力特性与反应。同时,应用结构有限元分析程序对模型及原型结构进行动力计算,并将两种结果进行比较分析。
The analysis of dynamic characteristics and seismic response of a high-rise control tower of airport with steel frame on the top is given from two respects ： model shaking table test and finite element calculation. A 1 ： 30 scaled model is tested to simulate the earthquake on shaking table. The dynamic characteristics and seismic response of the prototype structure are got by the similar 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.
