| 摘 要： | 本文提出了一种新的求钢筋混凝土框架结构设计最优解的混合法——坐标轮换法和模式搜索法合用。通过相应的程序处理,使无约束极值问题的优化算法可用于约束极值问题。在坐标轮换法的单维寻优中使用抛物线法,并且利用差商值之比判定框架梁、柱目标函数曲线的单调性,提高了寻优效率。

| Abstract: | A new hybrid method on the optimum solution of reinforced con-crete framed structure is put forward in this paper.In this methodthe coordinate transforation method and pattern search ethod areused in turn.By corresponding program manipulation,optimum algo-rithm of unconstrained extrema can be made to apply to constrainedextrema.The parabola method is used in the process ef one dimensionoptimum solution of the coordinate transformation method.And also,difference coefficient proportionality is made use of judge the objectivefunction curved monotone of the framed beam-column.The result isthat the efficiency of optimum solution is improved. |
