SAP2000 comparison of X-BF and EBF subjected to an imposed harmonic cyclic deformation (with a magnitude progressively increased to a maximum story drift equal to H/80).
FEM Model for Cyclic Inelastic Response of a Steel X-Braced Frame and an Eccentrically Braced Frame.
Nonlinear Direct Integration with nonlinear material behaviour and nonlinear geometry effect. Nonlinear Buckling for local and global effect.
Both braces have a very close initial stiffness and equivalent elastic limit force, please note degrading behavior in the X-Braced
