Seismic Response Modification Factor of Eccentrically Brace Steel Frame
Seismic response modification factor (R) and displacement amplification factor (Cd) are very important parameters to compute seismic force and to verify elasto-plasticity deformation in advanced seismic design. According to the present China Code for Seismic Design of Buildings,15 eccentrically braced steel frames are designed. R & Cd of 15 samples are computed by the Capacity Spectrum Method (CSM).Some correlative factors are analyzed and some reference is presented to the seismic design of these structures.
