The optimal design of fibre-reinforced plates having prescribed minimum specific fibre-volume has been obtained by Charrett and Rozvany.But the plastic speciality of optimal members at its minimum section was neglectd in their discussion so that optimality conditions might be inadequate.

Optimality conditions of a flexural member with lower bound on its cross section have been discussed by prager and Morz. The optimal design of fibre-reinforced plates having prescribed minimum specific fibre-volume has been obtained by Charrett and Rozvany.But the plastic speciality of optimal members at its minimum section was neglectd in their discussion so that optimality conditions might be inadequate. In this paper, the problem montioned above is studied again and the perfect Optimality conditions are obtained.These conditions are employed to design several beams and plates. The calculation result of the virtual work equality shows them to be adequate.

Prager与Mroz曾提出了具有最小断面限制的挠曲结构的塑性优化条件。Charrett和Rozrany作了具有最小断面限制的纤维配筋固支园板和简支园板的优化解。但是,由于他们当时没有注意到优化结构在最小断面处的塑性流动性质,因此[1]和[2]中的优化条件是不完善的。本文重新系统地研究了此问题,推证出挠曲结构在最小断面限制下完整的塑性优化条件。运用这些条件作了若干种梁、板的优化设计,由功能等式证明它们都是正确的。

As a matter of fact it is very difficult and unnecessary as well to findout the strict soluttions to the problems,which have arisen in the optimum designof structures in engineering science.What is required of us is to find out the po-ssible approximation of optimum design based on the initial structures,according tothe features of structure forms and the requirements for property specifications.On the basis of the above-mentioned idea,in line with characters of trussstructure optimum approximation of design and in the light of topology-finite-elementmethod of analysis,a linear model has been derived in relation to the design vari-ation,and,by applying Prager Oettli perturbation theorem and making a local per-turbation of design variation,a comprehensive method for making an optimum de-sign has been found.This method is comparatively simple and practicable,and at thesame time,it requires only a few number of calculations.No doubt,it can be expec-ted to raise economic efficency.

Combinig the strategies of costate prediction approach by Hassan and Singh and the time-delay coordination algorithm by Tamura, the variable prediction-time decomposition technique is put forward. Using the technique, the nonlinear three-level hierarchical optimization structure is formulated. The related conclusions proposed by the paper may also be used to solve other high dimensional nonlinear...
