阻尼器作为墙体连接件的装配式框-剪结构受力性能数值模拟

Numerical Simulation of the Mechanical Behavior of the Damper As a Frame-shear Wall Structure of Wall Connector

研究采用阻尼器作为墙体连接件的装配式框-剪结构受力性能,为该类结构的设计与施工提供理论依据。基于干式连接的方法,运用有限元软件ABAQUS,以一个采用灌浆套筒竖向连接的全装配式框架-剪力墙结构抗震性能试验模型为研究对象,将其墙体部分竖向拆分,并采用连续双圆孔软钢阻尼器连接,构建装配式框-剪结构有限元模型,研究装配时预留竖缝宽、位置对其整体结构承载力影响。结果表明,预留竖缝宽对装配式框-剪结构的承载力有影响,预留竖缝越宽,装配式框-剪结构承载力越低;预留竖缝位置对装配式框-剪结构承载力影响不大。可为相关的实际工程与试验研究提供理论参考。

Research on the mechanical performance of fabricated frame-shear wall structures using dampers as wall connectors provides theoretical basis for the design and construction of such structures.Based on the dry connection method,using the finite element software ABAQUS,a fully assembled frame-shear wall structure seismic performance test model with vertical connection of grouting sleeves is taken as the research object,and the wall part is vertically split.The continuous double circular hole soft steel damper connection is used to construct a finite element model of the assembled frame-shear wall structure.The influence of the width and position of the vertical joints on the overall structural bearing capacity during the assembly is studied.The results show that the width of the reserved vertical joint has an influence on the bearing capacity of the fabricated frame-shear wall structure.The wider the reserved vertical joint,the lower the bearing capacity of the assembled frame-shear wall structure;The bearing capacity of the frame-shear wall structure has little effect.It can provide theoretical references for related actual engineering and experimental research.
