摘要 为研究装配式拼装型减震墙板框架的减震机理与性能,设计4榀单层单跨装配式减震墙板框架、普通墙板框架和空框架模型试件,通过低周反复加载试验对比研究其破坏特征、滞回曲线、刚度退化和耗能能力等。试验结果表明:装配式拼装型减震墙板框架滞回曲线饱满、耗能能力强;拼装型减震墙板所提供的附加抗侧刚度和水平承载力有限,释放对装配式框架的过强约束作用,从而减轻或避免普通填充墙板附加刚度效应所带来的结构抗震不利影响;无论拼装与否,减震墙板通过合理构造与设计均可减小或避免大位移加载工况下墙板自身的破坏;拼装型减震墙板应注意墙板施工精度控制,否则会影响其减震性能,导致不必要的墙板破坏。

Abstract:To learn energy dissipation mechanism and performance of precast assembled damping wall-frame, four reduced scale specimens of one-story and single-bay precast frame including prefabricated damping wall-frame, conventional wall-frame and bare frame were designed and tested for a comparison of the failure characteristics, hysteretic curves, energy-dissipating capacity and degradation of stiffness of the specimens. Test results indicate that the precast assembled damping wall-frame exhibits rounded hysteresis loops and well-performed energy dissipation capacity; compared to the conventional wall, the assembled damping wall can provide less additional horizontal bearing capacity and lateral stiffness of the frame, and therefore, by releasing the excessive restraint to the assembled frame, the adverse effects in seismic resistance of structure attributed to the additional stiffness from conventional infill walls can be alleviated or even avoided; the damping wall with rational constitution and design, whether it is assembled or not, can performs well in the cases of large loading displacement; the construction precision for assembled damping wall shall be controlled, otherwise its damping performance may be impaired, so that some unnecessary damage of walls may be produced.
