摘　　要：本文提出一种微曲面网架结构型式及其最优表面形状的实用计算公式,并将网架曲面形状的优化设计问题归结为一个简单的非线性数学规划问题,为设计和应用这种网架结构型式提供理论依据.A structural type of space grid with small -curved surface is presented in this paper and some practical computation formulas are deduced for its optimizing the surface shape. The design problem is finally reduced to a simple nonlinear programming model. This paper provides a theoretical basis for applying such structural type of space grid in engineering practice.
