to design concrete sectional sizes of beams.the optimzation model
of the spatial frame is transformed into a problem of GGP(generalized geomeric progrmaming ) in terms of the Duffin's
condensation formula . Adopting the strategy of two stages. the
problem is solved by the structure stage and the elements stage ,alternately.

为了设计柱体的具体可组合大小，空间结构的优化的模型在Duffin的密集化公式的形式下被转化为一个GGP(通用几何体编程)。应用两种场景的策略，问题被结构场景和元素场景交替的解决。
