[1]Shaking table test on multi-dimensional seismic response of structure and nuclear power  equipment coupled system
Abstract/摘要：Structure and nuclear power equipment coupled system in nuclear power plant has complex dynamic interaction under seismic action. In order to study the seismic response of coupled system and assess seismic capacity of nuclear power equipment, shaking table test on coupled system by multi-dimensional seismic action was carried out. The natural frequency and damping ratio of the structure and nuclear power equipment were measured by two dynamic characteristic tests before and after the test. Furthermore, the test also included five operating basis earthquakes and one safe shutdown earthquake by using the artificial seismic waves as seismic inputs. The test results show that the dynamic amplification effect of the coupled system is obvious, and acceleration amplification factor of the equipment in the coupled system is about two times of the equipment directly connected to the shaking table in the X direction, between one and two times in the Y and Z direction. Compared with the structure, the dynamic response of the equipment in the coupled system also has a certain degree of amplification effect. In addition, the dynamic characteristics of structure and equipment change little. The equipment works well under all the test conditions, meeting the seismic requirements.
