摘要：
A shaking table test was performed on a full-scale model of a single-story fabricated light steel popular science building to obtain the dynamic characteristics including the natural frequency and damping ratio. Two actual seismic records and one artificial seimic wave were used in the test to obtain the seismic responses, including the acceleration response and displacement response of the model under different levels of earthquakes. The test results showed that the structural natural vibration frequency could be calculated using the method that the standards recommend; no significant change is observed in the natural vibration frequency and damping ratio of the building after subjected to earthquakes, which indicated that there is no degradation of the structural stiffness. It is further suggested that the damping ratio of prefabricated light steel structures in the elastic stage can be taken as 0.03. The test results also showed that no obvious deformation and failure are observed in the weak parts including the connecting positions such as the openings, end studs and lintels as well as the main lateral resisting components such as the wall frame and panels. The deformation of the house is found to be recoverable after test. The maximum elastic inter-story drift ratio of the structure under frequent earthquakes and rare earthquakes are 1/836 and 1/124, respectively, which meet the requirements of the Chinese code and showed good seismic performance of this structure. © 2019, Editorial Office of Journal of Building Structures.
