- Abstract:
-
The numerical method is used to discuss the calculation of stable limit load in the plane of wedge column, and the method of mixed iteration is adopted in the iteration condition to avoid the problem of iterative non-convergence in the calculation of cross-section M-P-Φ relation. The elastoplastic condition is applied to the calculation of the load-deflection relationship of the component, which optimizes the calculation process and shortens the calculation time. The change law of ultimate load with wedge rate and bending moment ratio at the end of the column was analyzed by using the program. The conclusions obtained can be used for the reference of designers.
