It was experimentally validated that partially debonded high-strength longitudinal reinforcement can provide strong self-centering capacity to minimize residual deformation, and greatly mitigate seismic damage of column. To continuously investigate the influence of partially debonded longitudinal rebars (PDLR) of column and beam on seismic behaviors of beam-column joint assembly, three interior and three exterior joint specimens were fabricated to subject to cyclic lateral loading. It was showed experimentally that joint specimens with PDLRs in both beams and columns had slighter seismic damages, smaller stiffness and energy dissipating ratios, better ductility compared with joint specimens without PDLRs in the beams. Furthermore, the lateral load of joint specimens without PDLRs in the beams decreased from lateral drift of about 4.0%–5.0% due to much crushing and spalling of concrete in the compressive zones of the beams. Whereas, joint specimens with PDLRs in the beams had continuously increased lateral load until lateral drift up of 10.0%. An analytical approach was derived to evaluate the lateral behavior of beam-column joint assembly which can considering joint deformation and steel bond slip. The proposed approach can reasonably predict the lateral behaviors of joint specimens with or without PDLRs. Analytical results indicate that approximately 70% of total deformation of joint specimens with PDLRs in both beams and columns is contributed by slippage deformation of the beams, whereas, that contribution ratio of the other joint assembly specimens is only 30%.

通过实验验证，部分剥离的高强度纵向钢筋可以提供强大的自定心能力，以最大程度地减少残余变形，并大大减轻柱的地震破坏。为了不断研究柱和梁的部分剥离的纵向钢筋（PDLR）对梁柱节点组合件的抗震性能的影响，制作了三个内部和三个外部节点标本，以承受周期性的横向荷载。实验表明，与在梁中没有PDLR的联合样本相比，在梁和柱中均具有PDLR的联合样本具有较小的地震破坏，较小的刚度和能量耗散率，更好的延展性。此外，梁中没有PDLR的联合试样的侧向载荷从大约4.0％–5的侧向漂移减小。由于梁的受压区中的混凝土被大量压碎和剥落，因此为0％。而在梁中带有PDLR的联合试样的侧向载荷不断增加，直到侧向漂移达到10.0％。推导了一种分析方法来评估梁-柱节点组合的横向性能，该方法可以考虑节点变形和钢粘结滑移。所提出的方法可以合理地预测有或没有PDLR的关节标本的横向行为。分析结果表明，在梁和柱中具有PDLR的联合试样的总变形中，约有70％是由梁的滑移变形引起的，而其他联合装配试样的贡献率仅为30％。梁中带有PDLR的联合试样的侧向荷载不断增加，直到横向漂移达到10.0％。推导了一种分析方法来评估梁-柱节点组合的横向性能，该方法可以考虑节点变形和钢粘结滑移。所提出的方法可以合理地预测有或没有PDLR的关节标本的横向行为。分析结果表明，在梁和柱中具有PDLR的联合试样的总变形中，约有70％是由梁的滑移变形引起的，而其他联合装配试样的贡献率仅为30％。梁中带有PDLR的联合试样的侧向载荷不断增加，直到横向漂移达到10.0％。推导了一种分析方法来评估梁-柱节点组合的横向性能，该方法可以考虑节点变形和钢粘结滑移。所提出的方法可以合理地预测有或没有PDLR的关节标本的横向行为。分析结果表明，在梁和柱中带有PDLR的联合试样的总变形中，约有70％是由梁的滑移变形引起的，而其他联合装配试样的贡献率仅为30％。推导了一种分析方法来评估梁-柱节点组合的横向性能，该方法可以考虑节点变形和钢粘结滑移。所提出的方法可以合理地预测有或没有PDLR的关节标本的横向行为。分析结果表明，在梁和柱中具有PDLR的联合试样的总变形中，约有70％是由梁的滑移变形引起的，而其他联合装配试样的贡献率仅为30％。推导了一种分析方法来评估梁-柱节点组合的横向性能，该方法可以考虑节点变形和钢粘结滑移。所提出的方法可以合理地预测有或没有PDLR的关节标本的横向行为。分析结果表明，在梁和柱中带有PDLR的联合试样的总变形中，约有70％是由梁的滑移变形引起的，而其他联合装配试样的贡献率仅为30％。
