| Abstract: |
| Objective To investigate the influence of rigid modal response on the results of MPRS seismic analysis. Methods The MPRS seismic analyses considering the rigid modal response and not considering the rigid modal response were carried out with software ANSYS15.0. And the foundation loads of the calculation were contrasted. Results Considering the rigid modal response had a relatively high effect on the supports of different elevations, especially for partial elevations. Conclusion Therefore, the influence of rigid modal response should be considered for the MPRS seismic analysis of this type of nuclear power equipment. |
