摘要:
为研究穿斗式木结构的抗震性能及其加固方法，选取杉木和松木两种木材，设计并制作四榀穿斗式木结构平面外框架，采用黏弹性阻尼器加固试件，对加固和未加固的木框架分别进行低周往复荷载试验，研究结构的抗震性能及阻尼器的加固效果。研究结果表明：加固后木排架滞回曲线的滑移和捏缩现象大幅减轻，滞回环面积增大，等效黏滞阻尼比增加，耗能能力增强,杉木和松木排架耗能能力分别提高83.31%和286.34%；加固后试件的骨架曲线斜率和极限承载力均得到大幅提升，斜率大致随加载幅值增大而增大，极限承载力杉木排架最大提升218.32%，松木排架最大提升458.89%；加固后木结构框架的刚度储备增高，初始刚度杉木试件提升46.9%，松木试件提升264.1%；杉木试件在安装阻尼器后节点的残余拔榫量减少15.06mm，松木试件减少31.96mm。
Abstract:
In order to study the seismic performance and reinforcement method of pairedcolumn timber structure, four sets of traditional Chinese timber frame models were designed and fabricated by selecting fir and pine wood. The specimens were strengthened with viscoelastic dampers, and the lowcycle reciprocating load tests were carried out on the strengthened and unstrengthened wooden frames respectively to study the seismic performance of the structure and the reinforcement effect of the dampers. The results indicate that the sliding and squeezing phenomena of the reinforced and unreinforced timber frames are significantly reduced, the area of the hysteresis loop is increased, and the effective viscous damping ratio is raised, resulting in an enhancement of the energy dissipation capacity. The energy dissipation capacity of fir and pine bent is increased by 8331% and 28634% respectively. The skeleton curves of the reinforced and unreinforced timber frames exhibit an increase in their slope and ultimate bearing capacity, which generally increases with the amplitude of loading. The initial stiffness of the pine and fir timber frames after the installation of the dampers is raised by 469% and 2641%, respectively. The residual protruding quantity of the nodes on the pine and fir timber frames after the installation of the dampers is reduced by 1506 mm and 3196 mm, respectively.
