装配式槽钢开孔耗能支撑是在中心支撑斜杆两端设腹板开孔槽钢构成，开孔槽钢与H型钢支撑之间采用螺栓连接，可避免中心支撑斜杆受压失稳。为了研究这种支撑的滞回性能，设计了3根开孔形式不同的装配式槽钢腹板开孔耗能支撑试件，对试件进行低周往复加载试验，并进行了有限元模拟分析。研究结果表明：在轴力作用下，装配式槽钢开孔耗能支撑主要依靠端部槽钢开孔腹板的孔间板件屈服耗能，整个加载过程中支撑主体H型钢未发生失稳；加载过程中螺栓出现了滑移，滞回曲线有不同程度的蔫缩；试验中腹板开椭圆孔的试件耗能能力最强 ...

基于双肢短剪切型耗能段、形状记忆合金（SMA）棒材的超弹性和碟形弹簧的恢复力，提出一种自复位双肢剪切型耗能段，可有效提高中心支撑结构的抗震性能和震后功能恢复能力。采用校正的有限元法对自复位双肢剪切型耗能段力学性能进行分析，研究其滞回性能和破坏模式；随后对考虑SMA棒材直径和碟形弹簧刚度的十个模型进行参数化分析。结果表明：自复位双肢剪切型耗能段具有良好的承载能力和自复位能力，以及较小的残余变形。拉力作用下，SMA棒材受拉且碟形弹簧静止；压力作用下，SMA棒材静止且碟形弹簧受压 ...

钢管混凝土叠合柱-H形钢梁外套筒式连接节点抗震性能试验与有限元研究
Jianzhu Gangjiegou Jinzhan以钢管混凝土叠合柱为研究对象，设计了一种高强对穿螺栓连接的外套筒式梁柱节点。为了研究该新型节点的抗震性能和破坏机理，进行了3个缩尺比为1：2的节点拟静力试验。观察节点损伤过程及破坏模式，分析梁端荷载-位移滞回曲线、骨架曲线、节点延性及耗能能力，采用ABAQUS软件建立有限元模型，研究套筒宽厚比和加强肋板厚度对节点抗震性能影响。试验及有限元研究结果表明：节点滞回曲线饱满，延性系数介于3.13~4.19之间，等效粘滞阻力系数介于0.211~0.296之间，节点域的变形和耗能能力较强；随着套筒厚度增加 ...
