摘要:

为实现剪力墙结构震损后的快速修复,提出一种水平缝钢制连接的可修复装配式剪力墙结构(Repairable precast shear wall with horizontal steel connections,RPW-HSC),采用ABAQUS软件对高宽比为1.0的RPW-HSC试件进行建模分析,数值模拟结果与试验结果吻合良好。通过有限元参数化建模,研究钢制连接中剪切板的厚度、开缝处小钢柱的高宽比、钢板强度及轴压比对RPW-HSC试件抗剪性能的影响,建立RPW-HSC抗剪承载力设计方法。结果表明:RPW-HSC试件的刚度与抗剪承载力随剪切板厚度、钢材强度及轴压比的增加而增加,但参数过大会导致该试件由钢制剪切板破坏转变为上部预制混凝土墙体破坏; 当钢制剪切板开缝处小钢柱高宽比小于3时,试件的破坏由开缝处小钢柱的弯曲破坏变成上部预制混凝土墙体的剪切破坏。因此,需控制合理的设计参数以实现RPW-HSC试件结构损伤可控及震损可修复。RPW-HSC试件抗剪承载力设计方法获得的理论计算值与试验值及有限元结果吻合较好,验证了抗剪承载力设计方法的准确性。

Abstract:

To realize structure’s reparability after being damaged by earthquakes,a reparable precast shear wall with horizontal steel connections(RPW-HSC)was proposed.The finite element model of RPW-HSC with the height-width ratio of 1.0 was established based on ABAQUS,the numerical simulation was in good agreement with the experimental results.The effects of the shear-plate thickness of steel connection,the height-width ratio of small steel column at the slit,the steel-plate strength and the axial compression ratio on the shear performance of specimen RPW-HSC were investigated by finite element parametric modeling,and the design method of shear-resistance bearing capacity of RPW-HSC was established.It’s found that the stiffness and shear-resistance bearing capacity of specimen RPW-HSC increased with the increase of shearing plate thickness,steel strength and axial compression ratio.However,excessive parameters caused the failure of the specimen changing from steel shearing plate damage to upper precast concrete wall damage.When the height-width ratio of the small steel column at the slit was less than 3,the failure of the specimen changed from the bending failure of the small steel column at the slit to the shear failure of the upper precast concrete wall.Therefore,it was necessary to control the reasonable design parameters to realize the controllable structural damage and earthquake-damage reparability of the specimen RPW-HSC.The theoretically calculated values obtained from the shear-resistance bearing capacity design method of the specimen RPW-HSC were in good agreement with the test values and finite element results,which verified the accuracy of the shear load capacity design method.
