为了给广府木结构的修复提供理论依据，采用菠萝格木材设计制作了5个箍头榫节点试件。考虑到榫卯构造尺寸的影响，首先进行了未加固无损节点的拟静力试验。然后，采用对原有外观影响较小的雀替型阻尼器对上述节点损坏试件进行加固，以尽可能保留建筑的原始风貌。最后，对加固节点进行拟静力试验，以研究节点的抗震性能变化以及阻尼器的加固效果。结果表明：采用阻尼器加固后的节点试件在加载至破坏时，榫卯处压痕明显，梁外榫外侧劈裂、脱榫现象明显，阻尼器脚部的橡胶与钢板有一定的脱离现象；对节点增设阻尼器能够弥补节点初期损伤导致的受力性能下降，为残损榫卯节点提供较好的后期刚度，提高节点的承载能力和耗能能力；与未加固试件相比，增设阻尼器后，试件的后期刚度、极限承载力、总滞回耗能均有所增加，分别提高18%、19%、20%以上。文中还在已有简化力学模型的基础上，结合OpenSees，提出了一种应用于箍头榫木结构的宏观模型建模方法。采用该方法得到的节点滞回曲线与试验结果吻合良好，可以有效模拟阻尼器加固的箍头榫木节点的滞回耗能特性。

To provide theoretical basis for the restoration of Guangfu wooden structures, five hoop head tenon joint specimens were designed and manufactured using Merbau wood. Considering the influence of the size of mortise and tenon construction, quasi-static tests were carried out on undamaged and unreinforced joint specimens. Then, to preserve the original appearance of the building as much as possible, the damaged joint specimens mentioned above were reinforced by the Queti-type dampers that have minimal influence on the original appearance of the structure. Finally, quasi-static tests were conducted again on the reinforced joints to investigate the difference in their seismic performance and the strengthening effect of the dampers. The results show that the joint specimens reinforced with dampers exhibit significant indentations at the mortise and tenon connections when being loaded to failure. There is noticeable splitting on the outer side of the tenon of the beam and the detachment of the tenon, as well as obvious separation between the rubber and steel plate at the base of the damper. The addition of dampers to joints can compensate the decrease in force-bearing performance caused by initial damage, provide better post-damage stiffness for the damaged mortise and tenon joints, and enhance the ultimate load-bearing capacity and energy absorption capacity. After adding the damper, there occur enhancements in terms of post-damage stiffness, load-bearing capacity and energy absorption of specimens, as compared with the unreinforced joints, with the increment being more than 18%, 19% and 20%, respectively. Moreover, on the basis of the existing simplified mechanical model and in combination with OpenSees, a macro-modelling method was proposed for hoop head tenon timber structures, which helps to obtain hysteresis curves of the joints being in good agreement with the experimental results, meaning that the modelling method can effectively simulate the hysteresis energy dissipation characteristics of the hoop head tenon joints strengthened with dampers.
