Time history response analysis of a multi-degrees-of-freedom system such as a single layer lattice dome with a substructure takes a lot of time. Therefore, the purpose of this paper is to examine the validity of response spectrum analysis that reqires less time in computation. The ABS method (absolute sum), the SRSS method and the CQC method were used for response spectrum analyses. Based on the result, we made clear the effect of substructure, half subtended angle of a dome and effective mass ratio on the earthquake response behavior. And then, the results of response spectrum analysis were compared with that of time history response analysis. In conclusion, the response values by the CQC method which takes modal correlations into consideration well correspond to the maximum response values by time history response analysis.
