摘　　要：比较了上海浦东机场(二期)候机楼在竖向地震一致输入和多点输入下的地震反应间的差异。通过屋面空间结构有代表意义的节点位移和杆件轴力的计算结果比较,探讨了在竖向地震多点输入下候机楼空间结构地震反应的变化规律,得出了一些有工程实践意义的结论。The difference between the seismic responses of Pudong Airport Terminal（ Ⅱ） obtained from uniform excitation and lnulti- support excitation is studied in this paper. By comparing the responses of the displacements of the representative nodes and axial forces of members of the space structure roof,the changing rules of the respective physical variables of those nodes and members under the action effect of seislnic multi-support excitation are studied, some conclusions for engineering practice are drawn.
