Study on structural influencing coefficient of eccentrically braced steel frame with replaceable energy dissipation links based on IDA method
To investigate the effects of cross-section size,beam length,number of stiffeners,and number of floors on the structural influence coefficient(R)and the displacement amplification factor(Cd)of ec-centrically braced frames with replaceable double-channel shear links,incremental dynamic analysis(IDA)was conducted on 18 models with varying parameters using the OpenSees finite element software.The structural influence coefficients and displacement amplification factors were calculated for each respective model.The results indicate that the seismic performance and deformation capacity of the eccentrically braced frame with replaceable double-channel shear links can be enhanced through the judicious design of the shear link structural parameters.Additionally,proposed values of R and Cd are provided to serve as a reference for further studies on the structural influence coefficient of eccentrically braced frames.
