Abstract:

高强钢组合K形偏心支撑钢框架通过低屈服点耗能梁段的弹塑性变形耗散能量,结构破坏主要集中于此,可通过更换耗能梁段完成结构修复。为研究替换构件法修复这种结构的可行性和修复后结构的抗震性能,先对1榀单层单跨1/2缩尺的高强钢组合K形偏心支撑钢框架进行循环加载试验;将已加载破坏的试件进行更换耗能梁段修复,再对修复后的试件进行循环加载试验。试件破坏模式和主要抗震性能指标的分析结果表明采用替换耗能梁段法修复这种结构是可行的,且修复工作量小,有利于尽快恢复正常;修复后的极限承载力与原试件相当,但延性系数略有降低;相同层间位移角下二者耗散能量差别不大,但修复后的耗能梁段转动能力不及原试件。
