文摘
- •
Dynamic Relaxation method is employed to compute the structural buckling limit load.
- •
By imposing the work increment of the external forces to zero, the load factor is found.
- •
The proposed formula only requires the fictitious parameters of the DR scheme.
- •
To verify the suggested algorithm, various geometric nonlinear analyses are performed.
- •
The authors' method can successfully estimate the buckling limit load of structures.
