摘要
根据集合的概念，由几何集Ｋ与本构集Ｃ求交集，即Ｋ∩Ｃ，再以此与平衡集Ｓ求三者的交集，即Ｋ∩Ｃ∩Ｓ．用此凸分析求条件极值的方法确定超静定结构的未知力，所得结果与其它方法完全相同．
Proceeding from the concept of set,the paper first tries to find the intersection of the geo-metrical set K and the constitutive set C,i.e. K∩C,and then the intersection of K∩C and the equilibriumset S,i.e.K∩C∩S.This is the method of using convex analysis to find the conditional extreme value. Themethod vvill ensure the same result in identifying the unknown forces in statically indeterminate system as re-gards other methods.
