装配式抗震框架延性节点的研究

Study on the Ductile Connections for Precast Aseismic Frame

为研究装配式抗震框架的延性节点行为，试验了4个试件．试件的设计体现延性节点行为的3种机理：拉-压屈服、摩擦滑移及非线弹性反应．扼要说明各试件的楼层剪力-层间位移角关系，某些试件的弯矩-转角关系及钢筋应力-应交关系，对试验结果和延性节点构造作了评价．

Four Subassemblages for aseismic frame were tested to investigate the behavior of ductile connections. Specimens were designed to incorporate three behaviolal concepts: tension/compression yielding, frichtion by slotting, andnonlinear-elastic response. A brief description of plots of storey shear versus interstorey drift for all specimens as wellas Plots of moment-rotation relationship and reinforcement stain versus stress for select specimens are presented. Theevaluation of the experimental results and the details of ductile connections is given.
