In order to study the inelastic behaviors of braced frames in which sway deflection due to column shortening and elongation is not negligible, an overall analysis is essential. This paper includes the method of static and dynamic analysis, in which the incremental member stiffness is determined according to generalized hardening hinge method. Overall inelastic static and dynamic behaviors of multi-story steel braced frames are examined by the present method. Braced frames which are analyzed are 10 story 3 bay frames and are designed according to the plastic design method which was already proposed in the previous paper (Part 1). Furthermore, response quantities of the braced frames are compared with those of plastically designed open frame. Numerical results show that the most of input energy is dissipated by bracing members. Therefore, inelastic dynamic dynamic responses of braced frames are considerably small and uniform along the height of the frame in comparison with the responses of open frame
