一种新型自复位耗能段的力学性能试验研究

open access: yesJianzhu Gangjiegou Jinzhan
基于扩孔螺栓连接型耗能段和自复位SMA支撑,提出一种新型自复位耗能段,具有强耗能、高延性、低残余变形和低损伤等特点,可进一步提高偏心支撑结构的抗震性能和震后功能恢复能力。分别设计3个考虑摩擦滑移的自复位耗能段和1个普通自复位耗能段试验模型,并进行往复加载研究,得到其变形或破坏模式、滞回曲线和骨架曲线等。结果表明,滑移阶段耗能段处于相对静止状态,所有构件均处于弹性;非滑移阶段中耗能段依次发生滑移、屈服、翼缘和腹板屈曲现象,整个过程中自复位SMA支撑中SMA受拉,并为自复位耗能段提供承载力、耗能能力和复位力。
