建筑结构框架梁的非线性规划解

摘要

针对钢筋混凝土框架梁, 将非线性优化设计问题转化为几何规划问题, 并导出了钢筋混凝土框架梁截面优化设计的计算公式. 算例结果分析表明, 方法具有较好的实用价值.%The problem of the nonlinear optimal design is reduced into a geometrical programming problem for the reinforced concrete frame beam,and the related formulas for the cross-section optimization design of reinforced concrete frame beams are derived.The numerical example shows that it is practical.
