| Abstract: | The multi-assumed-spring method is developed to solve the negative stiffness problem of softening structures.This scheme has direct physical sense and can be programmed concisely.It is applicable in the numerical analysis of a structure subject to multi loads for the whole loading and unloading processes with controlled load proportion.A few cases are studied with this approach,which shows that it has good feasibility and convergence. |
