Elastoplastic seismic response analysis of a high-rise eccentrically braced frame structure

Eccentrically braced frames have larger lateral force resistance rigidity to unbraced frames and can effectively reduce the earthquake effect to centrically braced frames.Quite a few study of eccentrically braced frames has been given,but has seldom been put into practice.Which at present,in steel structure,is mostly centrically braced frames or unbraced frames.With a practical example,elastoplastic time-history analysis and the seismic performance of the high-rise eccentrically structure was accomplished.
