| 摘 要： | 考虑锚栓服役时实际参与抗剪这一特性,给出了柱底板是否需要设置抗剪键的简易判断方法。在阐述柱底板与抗剪键间连接焊缝的承载能力机理的基础上指出连接焊缝是处在拉力和剪力共同的作用下,沿焊缝方向不会形成薄弱环节;同时针对工程中柱基常采用的3种不同构造形式,提出不同构造形式应采用不同的摩擦系数。

| Abstract: | Considering the characteristic of anti-shear of anchor bolt when it is serving, a simple method is presented in deciding whether a shear key is needed. It is also described the load-carrying mechanisms of connection weld between shear key and column plate, from which it is opened out that it is the combination response under the load of tension and shearing force that decides. So it is recognized weakness that may not be formed along weld direction. At the same time, different friction coefficient should be used for three different types of formation of column base in projects. |
