| Abstract: | The stressed-arch frame is a new type of prestressed steel structure system.In this paper,the analysis method for the stressed-arch frame from form-finding to load computation was researched;the theoretical formula considering geometry nonlinear and material nonlinear was deduced.As a resent,at the same time,the special program for the new structure has been developed,whose correctness is verified by comparison with the foreign research report. |
