摘要
文中以时程分析方法,通过数值计算研究了上海浦东机场(二期)候机楼的竖向地震行波效应。计算结果给出了屋面空间结构有代表意义的节点位移和杆件轴力的行波效应变化曲线,还给出了柱钢-混凝土节点和Y型钢节点的弯矩和轴力的行波效应变化曲线,探讨了这些节点和杆件的相关物理量在竖向地震行波作用下的变化规律,得出了屋面空间结构和柱节点的地震行波效应趋势和相应的行波效应影响系数和一些适于工程应用的结论。
By using the numerical method, the time-history analysis of the effect of vertical seismic traveling-wave at Pudong Airport Terminal （ II ） in Shanghai is studied. Calculation is done and the curves of the responses of the displacement of the representative nodes and axial forces of members of the spatial-structure roof are given, and that of the moments and axial forces of the steel-RC nodes and Y-type steel nodes of columns are also given. The changing rules of the respective physical variables of those nodes and members under the action of vertical seismic traveling-wave are studied. The trend of the effect of vertical seismic traveling-wave on the spatial Structure roof and nodes of columns, as well as respective effect factors is indicated. And some conclusions for engineering are drawn.
