改进满应力齿形法的钢箱梁截面优化程序设计
|
摘要
针对整体装配式钢-混组合连续梁桥,基于面积匹配思想与满应力法结合,建立了钢箱梁截面参数的优化设计模型。运用Matlab对组合连续梁桥钢箱梁进行优化,提出对应于不同跨径钢箱梁截面设计参数的初步优化取值。结果表明:本算法将离散的钢箱梁截面尺寸变量处理生成面积数据库,在迭代过程中嵌入面积匹配过程,可有效提高计算效率且收敛速度较快。
For the integral prefabricated steel-concrete composite girder bridge,an optimized design model for the section parameters of the steel box girder is established based on the combination of area matching and full stress method. By using MATLAB to optimize the steel box girder of the composite continuous girder bridge,a preliminary optimization value corresponding to the cross-section design parameters of different span steel box girder is proposed. The results show that this algorithm uses discrete steel box girder cross section dimensional variables to generate an area database. The embedding the area matching process in the iterative process can effectively improve the calculation efficiency,and the convergence speed is faster.
