- 摘要： In view of evaluation about the effect of base isolation on the seismic
performance of the nuclear power plant building,this paper,for the first
time,explores division of seismic performance indexes of nuclear power
plant auxiliary building,establishes numerical model of isolated and
non-isolated nuclear power plant building on hard soil ground,obtains
vulnerability curves based on IDA and MAS methods respectively,carries
out seismic vulnerability comparative study of isolated and non-isolated
structures based on the indexes and demonstrates the higher
anti-collapse safety reserve of the isolation measure. The results show
that: the results obtained by the two methods are basically
consistent,which proves the rationality of the results. Isolation
bearing can significantly reduce the failure probability of nuclear
power plant building and maximum of decrease amplitude can reach 23%,and
collapse probability of isolated factory building under major earthquake
can reduce 80% than that of non-isolated factory building. The safety
reserve coefficient is increased by 11% and failure probability of
concrete plays a controlling role in the overall failure probability of
the two kinds of factory building. - 备注： 新增回溯数据
