| Nowadays, it is of importance to keep continual development. Therefore, it is advocated saving resources ^ using space fully and freely and improving the service efficiency of structure material. In this paper, nonlinear finite analysis theory on prestressed concrete frame with special-section column is studied based on a great deal of study result on special-section column and fundamental theory such as nonlinear mechanics for reinforced-concrete and prestressed structure, in which a simple model for calculating is proposed and a quite correct and general method to describe the mechanical feature of a working prestressed concrete frame with special-section column is discussed. Then expatiate the process of analysis and calculation to the structure and design computer programme with FORTRAN90. Then after the programme is validated, the structure feature of prestressed concrete frame with special-section column is analyzed and discussed with various kinds of loading and with deferent factors such as column section > span> quantity of steel in column > quantity of prestress steel in beanu form of prestress steel and prestress level by plenty of result of calculating with computer. Then according to the study on structure feature of the frame, give out certain design method which is rather instructional when select proper structure form, design section ofstructure element, decide the form of prestress steel and decide proper prestress level.
