THE SEISMIC PERFORMANCE ANALYSIS OF REPLACEABLE INDEPENDENT LINKS

  • 摘要: 带可替换耗能梁段的偏心支撑钢框架结构与传统的偏心支撑钢框架结构相比,修复替换既方便又经济,目前国内外关于这方面的研究很少。运用ABAQUS有限元软件对8根参数不同的可替换耗能梁段进行了单向加载和循环往复加载分析,结果表明:加劲肋间距对可替换耗能梁段承载力的影响并不大,可替换耗能梁段长度的增大会引起承载力的减小;单向荷载作用下,可替换耗能梁段的位移延性系数和转角延性系数均较大,具有良好的延性;循环荷载作用下,可替换耗能梁段的滞回曲线饱满,没有明显的捏缩现象出现,具有较好的耗能性能。
    Abstract: The repair of Eccentrically Braced Steel Frames with replaceable link is convenient and economical compared with traditional Eccentrically Braced Steel Frames, and the research on replaceable link is limited worldwidely. In the paper, finite element analysis was performed for the one-way loading and cycle loading of eight replaceable link beams with different parameters using ABAQUS. Analysis results indicate that the space between ribbed stiffeners has small influence on the bearing capacity of replaceable link beams and the increase of replaceable link beam length causes the decrease of bearing capacity; Under monotonic loading, large displacement ductility coefficients and large angle ductility coefficients of replaceable link beams were obseved, showing good ductility; Under cyclic loading, the hysteresis curves of replaceable links are plumper with no pinch, showing good energy dissipation property.
