【摘要】 偏心支撑结构中的耗能梁段在正常使用阶段或小震作用下保持在弹性范围,在强震作用下通过其塑性变形消耗地震能量,避免结构整体破坏,震后只需对耗能梁段进行修复或更换,大大缩短震后结构修复时间,节约成本。作为耗能构件,为了适于震后修复和更换,偏心支撑框架耗能梁段在未来的研究中逐步引入可替换构件、铸钢整体浇铸制造等设计概念,为其应用提供更广阔的的前景。更多还原

【Abstract】 Eccentrically braced link beams remain in the range of elastic response during normal service stages and under the small earthquakes,while dissipate earthquake energy through plastic deformation when strong earthquake takes place,avoiding damage on the whole structure. Link beams are the only components that need to be repaired or replaced after earthquake,which can shorten the time to rebuid and save costs significantly. Eccentrically braced frame is widely used in the high seismic intensity zone with excellent ability of energy dissipation and seismic performance.更多还原
