This is particularly obvious for very tall structures where the lateral forces are the most important design consideration. Thus, no special wall detailing is required to allow for brace buckling deformation. 1 minute both, braced frame and moment resisting frame are used in the construction of structures which are subjected to lateral loads such as wind and seismic forces.

This paper summarizes the seismic design of three scbfs with different heights, namely, 4, 10, and 20 stories, at different sites. The columns act as the chords in resisting the overturning moment, with tension in the windward column and compression in the leeward column. Document on brace frame design, design examples, and november 1999 seaosc presentation served as the initial foundation for this edition of steel tips.
