摘　　要：介绍了一幢三层框架结构模型的地震模拟震动台试验.结构模型缩比为1/10,该框架带有两个相互垂直的楼梯.输入不同加速度峰值的地震波直至破坏.通过试验研究,了解了此框架结构的破坏特点,相互垂直楼梯对地震波的响应以及对框架结构的影响,此外,通过白噪声扫描的方法测定模型在经历不同峰值地震后的自振周期及阻尼的变化.试验结果可为框架结构抗震研究与设计提供参考依据.A test on shaking table of three- stairs was introduced. The reduction sca ayer frame model with two mutually perpendicular e of the model is 1/10. Different peak ground accelerations were input until the model was damaged. Through the test and analysis, we can understand the characteristics of the frame damage during earthquake, the response of the mutually perpendicular stairs to the seismic wave and their impact on the frame. In addition, we can understand the change of the frame in free vibration period and damping property after earthquake by White Noise scan method.
