| Abstract: | Y-eccentrically braced steel frame is the steel structure of eccentrically braced steel frames with well seismic-resistance and energy-dissipation. A new analytical model which includes degenerate shell element applied to link beams with large deformation and plastic deformation and beams element applied to other parts of structure is used for analyzing Y-eccentrically braced steel frame's energy-dissipation behavior. Computer program is complied and suggestions on seismic design are presented. |
