水泥窑尾预热器塔架的钢平台板在承受水平荷载作用时存在稳定性问题。采用非线性有限元法,对单向及双向角钢加劲的典型钢平台板块的稳定性能进行研究,确定竖向及水平两个方向荷载共同作用下钢平台板块的稳定承载力,给出了角钢加劲钢平台板块的稳定承载力的实用设计公式。
The steel platens of the cement kiln tail preheater tower have the stability problem when they are under horizontal load. The nonlinear finite element method is used to study the stability of typical steel plate with one-way and two-way angle stiffeners. The steady bearing capacity of steel plate under both vertical and horizontal loads is determined. Practical Design Formula of Stable Bearing Capacity of Steel Plate.
