“…According to the investigation and measurement on the site of TMSR-LF1 by the China Earthquake Administration [28], the seismic fortification intensity of the site is 7°; thus, the seismic fortification intensity was set to 8°in the seismic analysis. The peak ground acceleration (PGA), as a widely utilized ground motion intensity [29][30][31], is adopted as the intensity index in this paper. The maximum value of the horizontal earthquake impact coefficient can be determined from the PGA with the following formula:…”

The seismic performance analysis of research reactor plants is crucial for ensuring the safety of the entire reactor system. This paper analyzes the plant structure seismic performance of the 2WMt Thorium Molten Salt Reactor-Liquid Fuel 1 (TMSR-LF1) at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences under the action of frequent earthquakes, fortification earthquakes, and rare earthquakes was analyzed by finite element software PKPM based on the seismic design method of civil code +1°. On this basis, a comparison was made between the seismic responses of structural pushover analysis and elastoplastic time history analysis under the action of rare earthquakes, and the conservatism of these two commonly used methods for elastoplastic analysis was systematically analyzed. The results indicate that the TMSR-LF1 plant structure exhibits well bearing and deformation capacity. It meets the seismic design goal of “no damage under small earthquakes,” “no unrepairable damage under medium earthquakes,” and “no collapse under large earthquakes (using static pushover analysis),” and the critical regions are entirely within the elastic range. Furthermore, the analysis reveals that the elastoplastic time history analysis method produced a significantly higher seismic response than the pushover analysis method, which indicates the conservativeness of the time history method. Therefore, it is recommended to use the elastoplastic time history analysis method to evaluate the seismic performance of research reactor plants under rare earthquake actions. The research in this paper provides important references for the seismic performance analysis of other Class II research reactor plants.

“…Previous studies also indicated that if diagrid systems are designed in accordance with current standards, they generally exhibit a better performance in terms of shear lag and storey drifts compared to other types of tubular structural systems [25]. While there are some studies conducted on the analysis of progressive collapse in such systems [26,27], less information is available on the seismic reliability and design parameters suitable for performance-based design procedures.…”
