| Abstract: | Based on the reference4], the topological optimization problem of plane continuum structure under multi\|loading case with stress constraint has been solved according to the exist\|null combination model. The effective coefficient of loading case is proposed to identify and deal with the ill load problem. The computational results are satisfactory. |
