Jianzhu Gangjiegou Jinzhan可替换剪切耗能梁段作为与偏心支撑钢框架分离设计的独立耗能部件，不仅能在大震发生时将结构的塑性变形局限在耗能梁段区域内，更重要的是可以方便震后对结构的修复。文中制作了3榀该钢框架结构的缩尺模型，并对其进行了单向振动台试验，得到了结构的动力特性、塑性发展情况及破坏机理，并对模型的应力分布、位移响应、加速度响应等进行了分析研究。结果表明：该模型具备良好的耗能性能，剪切耗能梁段与防屈曲支撑构件分批耗能使得结构在地震作用下有较好的抗震性；带有可替换剪切耗能梁段的防屈曲偏心支撑钢框架构件的最大层间位移角符合规范要求，

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
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 ...
