摘要
满应力设计法是型钢桁架优化的最直接和最有效的方法之一,但优化计算过程复杂,计算效率低。与有限元法相结合,采用满应力设计理论编制了桁架优化设计通用程序,可以对各种类型、各种形状的桁架结构在多种工况下进行自动优化设计,大大提高了优化运算效率。
The rule of full stress is the most direct and effective method of the optimal design for shape steel truss.But the computation process is difficult and the computation efficiency is low.Combined with finite element theory,the general program is studied by the optimal theory of the rule of full stress. Through this program,the truss with different kind and different shape in various load case is designed au-tomatically,the computation efficiency is increased greatly.
