Paper Title:
Response Modification Factor for Y-Eccentric-Braced Steel Frame Structures
  Abstract

In current seismic design procedure, structural base shear is calculated according to the linear elastic response spectra divided by response modification factor R. The response modification factor is important to the reliability and economy of building seismic design. In this paper, the response modification factors of Twelve Y-eccentric braced steel frames with various stories and spans lengths were evaluated by capacity spectrum method based on the global capacity envelops obtained from an improved pushover analysis and incremental dynamic analysis. According to the results, an appropriate formula of the response modification factor for the Y-eccentric braced steel frames was suggested.
