vertical member meaning in English

垂直杆件
垂直构件
垂直机构
竖杆
竖向构件

So , because of the distinctness of vertical displacement of each vertical member of the same floor , then member model is presented to analyzing the vertical vibration during the vertical seismic action
因此，由于各竖向构件在同一楼层处竖向位移不同，需要用串并联多质点系模型来分析竖向地震作用下的竖向振动。
The floor of the high - rise frame structures is very suppleness when the frame structures subjected to the vertical seismic actions , it is impossible to confirm that each member has the same displacement in the same floor , so it is impossible that the summation of axes stiffness of each vertical member represent the global vertical stiffness of the frame structure
高层建筑框架结构在竖向地震作用下，楼板在竖向刚度是很小的，一般不予考虑，认为相对无限柔性，而梁的刚度也是有限的，不可能保证各竖向构件在同一楼层竖向位移相同，因此不能简单地用各竖向构件轴向刚度之和来代表结构的总竖向刚度。
