Abstract:
As a new anti-seismic structural system, the relevant structural behavior factor of high strength steel composite
eccentrically braced frame, has not been introduced into current Chinese seismic code, 4 multistory high strength steel composite
Y-type eccentrically braced frames were designed on the basis of Chinese seismic code. The incremental dynamic analysis was
carried out to get the global capacity spectrums of each model, and then the structural behavior factors R and the displacement
amplification factors Cd were calculated by the improved capacity spectrum method. The seismic performance of the structures was
studied. It was found that the structural deformation under moderate and rare earthquake can meet the requirements of Chinese codes.
The value of the structure behavior factor is 4.889, and the value of the displacement amplification factor is Cd=6.693. It’s
conservative to design the new structural system based on the current Chinese codes.
