摘要
就设计变量包括索力值的预应力索-桁架截面尺寸优化设计问题,考虑了荷载两阶段的约束条件,建立了相应的数学模型,提出了新的求解方法。算例表明该方法是有效的。
It is discussed prestressed cable-truss optimization design with its design variables including cross-sectional size and cable pretension force; and constraint conditions of the two stages of load are considered, a relevant math model is founded, and a new mothed of its .solution is put forward. The examples in this paper indicate that the mothed is effective.
