| 摘 要： | 对五层方钢管混凝土框架结构模型进行有侧向支撑和无侧向支撑的模态试验，采用多点激励单点输出的方法得到其频响函数，进而获得了结构的动力特性参数(频率、振型和阻尼比)。将试验数据与ANSYS分析结果进行对比，二者符合较好。研究表明，模态试验方法得到的结果能够为钢管混凝土框架结构的抗震设计提供重要的参考依据。

| Abstract: | In order to study the dynamic behavior of concrete-filled steel tubular frame,the modal experiment on the five stories with this system was carried out. By means of multi-point input and single-point output measurement, the transfer function was gained,then the dynamic parameters of the modal were identified including natural frequency,mode and shape damping ratio. Comparing the data of the experiment with those of the ANSYS,the result shows that the modal experimental research can supply the designers of this system with valuable reference data and provide necessary basis for evaluating the anti-seismic property factors of the design of CFST system. |
