- •
A Cyclic Explicit Dynamic (CED) procedure is devised for inelastic analysis of braced frame systems.
- •
Buckling and post-buckling responses via monotonic and cyclic loadings are accurately captured.
- •
CED is validated/verified against experimental data and numerical results.
- •
Yield mechanisms and formation of failure modes are recovered accurately by CED.
- •
CED can be used to assess nonlinear performance and to seek the optimum design criteria.
