    • Abstract
  • The mode energy participation coefficient in time domain is presented in this paper. The dominant modes of Beijing National Stadium (abbr. BJNS) are identified by the energy participation coefficients and the cumulative coefficients. Then the wind-induced responses of the dominant modes of BJNS are analyzed by time history analysis method. The covariance matrix of dynamic responses for the dominant modes is calculated, and then the displacement variances and peak factors of the structural nodes are determined. The mode-based time history analysis method presented in this paper improves the calculation efficiency and guarantees the precision of the calculated results.
