摘 要: | 对承受不同横向载荷的带筋板进行系列剖面优化设计,获得带筋板的初步设计尺寸,借助有限元计算从局部与整体屈曲角度对铝合金带筋板尺寸进一步优化,并确定具体的尺寸,有限元计算分析结果表明,所设计的不同规格的带筋板具有相同的应力水平,并计算得到其极限承载能力.

Abstract: | The sheet-with-ribs under different levels of lateral loads were optimized by theoretical method to get the preliminary scantlings of the sections.Buckling behavior of local plate and overall panel of the sheets-with-ribs under the uniaxially compressed loads were calculated by FEM to optimize the scantlings further.Numerical results of nonlinear FEA showed that the stress level of designed sheets-with-ribs with different scantlings is nearly same.The ultimate bearing capacities of the sheets-with-ribs can ... |
