Special shaped R.C. columns have been used widely in civil engineering field in recent years on account of their superi- ority. In this paper, carrying capacity of special-shaped columns under bi-directional eccentric load is discussed and programs are de- veloped as well. Compared with PKPM, the results are satisfied. The objective function is the cost of the major structure. The variables are extensive and the constraint conditions are based on the codes in force. Then, multi-level optimal design method based on the crite- ria method is introduced and grid-research method is in its search technique. Different efficient variables are set in different levels of optimal procedure, so that the optimal result conforms to the need of practical designing work. Finally, a column frame structure shaped multi-level optimization procedure is written.
