Eccentrically Braced Frame Design for Moderate Seismic Regions


Abstract eng:
Factors influencing the design of eccentrically braced frames when the seismic load does not play a primary role in the member selection are discussed. The influence of seismic overstrength is considered. Twenty-two frames with chevron configuration of eccentrically braced lateral force resisting systems are designed to investigate the influence of structure height, link length and various levels of the ratio of wind to earthquake load. These structures were analyzed under monotonic and dynamic lateral loads. It is concluded that smaller link seismic overstrength factors may be used for brace and column design in moderate seismic regions than currently specified in the design standard. The lesser ductility demands experienced also suggest that the detailing requirements for short links can be relaxed.
