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。

At the same time, performance of two-way composite slab with different boundary conditions and different span-ratio are analyzed.
同时，分析了双向组合板在不同约束条件和不同跨度比下的受力性能。

This paper discusses a new spatial structure-composite grid slab column structure, which is designed to transform single way force into two-way force to form a spatial forcing system.
