Dimensional optimization of reinforced circle plates and rings subject to symmetrical loads is presented based on duality between limit analysis and limit design,employing a model combining Morley curvature field in layout optimization and Powell Constrained Variable Metric Algorithms(CVM) in NLP.
基于理想刚塑性材料极限设计的对耦原理，将准则优化方法中Ｍｏｒｌｅｙ最优曲率场准则与数学规划技术中Ｐｏｗｅｌ约束变尺度法结合起来，解决了钢筋混凝土圆形、环形板式基础外形尺寸的优化设计问题，实现了抗弯与抗冲切的同步优化。
