    摘要:

    针对新型装配式剪力墙结构,以轴压比和边缘构件纵筋配筋率为对照参数,设计了3个缩尺比为1∶1.54的剪力墙试件并进行了拟静力试验。试验结果表明,3个试件的最终破坏模式相近,表现为墙体斜裂缝开展至受压区混凝土剥落的弯剪破坏;轴压比的减小或边缘构件纵筋配筋率的降低均对新型装配式剪力墙抗震性能有不利影响,表现为滞回性能减弱和极限承载力降低。结合有限元模拟结果,建立了新型装配式剪力墙的五折线骨架模型及恢复力模型,该模型与试验结果吻合较好,可以为新型装配式剪力墙结构的弹塑性地震反应分析提供参考。

    Abstract:

    Based on the construction advantages of dry connection mode of precast shear wall with high-strength bolts, steel plates and other components, a new type of prefabricated shear wall with the function of friction energy dissipation was proposed. Three shear wall specimens with the scale ratio of 1.54 were designed, and the control parameters were the axial compression ratio and the longitudinal reinforcement ratio of edge components. The quasi-static tests were carried out and the results show that the final failure mode of the three specimens are similar, which is the bending-shear failure that diagonal cracks in the wall develop to the concrete spalling in the compression area. The reduction of axial compression ratio or longitudinal reinforcement ratio of edge components have adverse effects on the seismic performance of the new prefabricated shear wall, which is manifested in the weakening of hysteretic performance and the reduction of ultimate bearing capacity. Combined with the finite element analysis results, the five-fold skeleton model and restoring force model of the new prefabricated shear wall were established. The proposed restoring force model is in good agreement with the test results, which can provide reference for the elasto-plastic seismic response analysis of the new prefabricated shear wall.
