摘　　要：测试一轻钢结构住宅足尺结构模型在环境激励的响应信号,通过频谱分析得到结构模型的自振频率,为验证所得自振频率的准确性对结构模型进行简谐波激励直到其产生共振,进一步分析得到结构模型的振型、阻尼比等动力特性,为研究结构模型的抗震性能提供参考依据。This paper presents the method to test the impulse response signal of a light steel structure residence modal under ambient excitation, natural frequency obtained according to spectrum analysis, the accuracy of the data were verified through the vibration reactions of the structure modal under the harmonic excitation, moreover the dynamic characteristic of vibration mode, damping ratio etc of the structure modal can be obtained, the conclusion could be used as a reference for the further study on seismic behavior of the modal.
