摘要: 土壤-结构动力相互作用(SSI)分析及楼层反应谱(FRS)计算是中国先进研究堆(CARR)工程抗震设计的重要环节。本文采用直接法,通过建立二维土壤-结构共同工作计算模型,并分3个方向进行地震动输入,考虑土壤-结构相互作用对反应堆厂房地震反应进行分析,计算出厂房基础部位和各楼层在不同工况下的地震反应及楼层反应谱。

Abstract: Analysis of Soil-Structure Interaction（SSI） and calculation of Floor Response Spectrum（FRS） is substantial for anti-seismic design for China Advanced Research Reactor（CARR） project.The article uses direct method to analyze the seismic reaction of the reactor building in considering soil-structure interaction by establishing two-dimensional soil-structure co-acting model for analyzing and inputting of seismic waves from three directions respectively.The seismic response and floor response spectrum of foundation and floors of the building under different cases have been calculated.
