钢基板与基砂浆之间的剪切摩擦对标准柱基的抗剪性能起着重要作用。AIJ设计规范中剪切摩擦系数取0.5，但相关背景数据有限。为了研究基板和砂浆之间的动态抗剪性能，研究人员使用了一个由钢接触元件支撑的大刚体，该刚体位于固定在振动台上的砂浆表面上。考虑了不同量级和频率的水平输入加速度。结果表明，滑动过程中摩擦系数恒定，平均值为0.78。并与以往的试验结果和数值分析结果进行了比较，发现两者之间具有良好的相关性。
Shear friction between the steel base plate and base mortar contributes to the shear resistance of standard column bases. A value of 0.5 is adopted as the coefficient of shear friction in AIJ's design specifications, but the associated background data are limited. To investigate the dynamic shear resistance behavior between the base plate and mortar, a shake table study is undertaken using a large rigid mass supported by steel contact elements that rest on mortar surfaces fixed on the shake table. Horizontal input accelerations are considered for various magnitudes and frequencies. The results provide a constant friction coefficient during sliding with an average value of 0.78. Comparisons with previous test and numerical analysis are also carried out, and good correlation among them is noticed.
