摘要:

利用数值方法对楔形柱平面内稳定极限荷载的计算进行了探讨,在迭代条件中采用混合迭代的方法,避免了在截面M-P-Φ关系计算中迭代不收敛问题;在构件的荷载- 挠度关系计算中应用弹塑性条件,优化了计算过程,缩短了计算时间;并利用程序分析了柱子的极限荷载随楔率与柱端弯矩比的变化规律.所得结论可供设计人员参考.

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.
