The external wall of a warehouse is a reinforced concrete two-wayslab which has one simply supported end and three fixed ends, bearing load of triangle.
堆场类建筑的外墙一般按照三边固定一边自由的混凝土双向板，板承受荷载为三角形荷载。

Designing as the one-wayslab, we should still set distributing concrete on the vertical direction of the stress except the loaded concrete along the stress direction.
当按单向板设计时，除沿受力方向布置受力钢筋外，尚应在垂直受力方向布置分布钢筋。

Considered within the framework of the ideal line flexibility, this paper derives the analytical expression of the one-way cable-slab structure's internal force calculation in the vertical load.
