摘要
针对某一具体工程,利用ABAQUS软件建立计算模型,模拟分析了粘滞阻尼器支撑墙的受力情况,分析了不同的粘滞阻尼器支撑墙水平和竖向分布钢筋配筋率、支撑墙暗柱配筋以及支撑墙墙体长高比等因素对粘滞阻尼器支撑墙受剪受力状态的影响。数值分析结果表明:粘滞阻尼器支撑墙墙体内配置钢筋可以显著的改善支撑墙受剪受力状态,但墙体水平、竖向分布钢筋配筋率和支撑墙暗柱配筋率大小对墙体的整体抗剪承载力影响不大,粘滞阻尼器支撑墙抗剪承载力基本保持不变;粘滞阻尼器支撑墙墙体长度的改变可以显著地改变墙体受力模式:长高比变长,墙体从受弯受力状态逐渐向受剪受力状态过渡,支撑墙的抗剪承载力得到提高。
ABAQUS software is used to establish a calculation model to simulate and analyze the stress situation of retaining wall with viscous dampers.The influence of different horizontal and vertical distribution of reinforcement ratio,concealed columns reinforcement ratio and wall length on the stress situation of the wall is analyzed.The results show that the reinforcement ratio have little influence on the shear capacity of the supporting wall and the change of wall length can change the stress mode of the wall and improve the shear capacity of the supporting wall.
