为促进建筑工业化和住宅产业化，提高框架-支撑结构体系的抗震性能，提出了部分包覆钢-混凝土组合（partially encased composite brace， PEC）支撑。对3个采用PEC支撑的PEC框架试件和1个采用钢支撑的PEC框架试件进行了低周往复加载试验，研究了各试件的破坏模式、初始刚度、极限承载力、耗能能力等指标。结果表明：PEC框架与PEC支撑之间协同工作性能良好；PEC支撑试件相比纯钢支撑具有优势，初始刚度提升约24%~41%、极限承载力提升约29%~36%，耗能能力提升约7%~17%

框架结构在地震作用下易在柱脚形成塑性铰，构建损伤可控且具有复位能力的柱脚节点可有效提高框架结构的抗震性能和韧性。基于工程实用的螺栓和盖板连接，提出了碟簧螺栓和屈曲约束翼缘盖板，分别作为恢复和耗能元件，形成一种碟簧螺栓连接柱脚节点。推导了节点的理论滞回模型以及部分构件的内力计算公式，采用ABAQUS软件建立了节点有限元模型并进行了滞回分析。结果表明，提出的节点滞回曲线呈典型的旗帜型，损伤集中于屈曲约束翼缘盖板的核心板，碟簧螺栓有效地降低了节点残余变形；有限元模型与理论滞回模型相互验证，两种结果吻合较好 ...
