Abstract:  In a limited precision and in the scope of practical velocities of seismic wave, the continuous curves of the responses of the displacement of the representative nodes and axial forces of members of the space structure roof of Shanghai Pudong airpont terminal  II are gjven, and that of the moments and axial forces of the steel-RC nodes and Y-type steel nodes of columns are also given. After the changjng rules of the respective physical variables of those nodes and members under the action effect of seismic travelingwave are studied.Some conclusions for engneenng practice are drawn.
Keywords:  long-span space structure; horizontal seismic action; uniform excitation; traveling-wave; time-history analysis
