抗滑移荷载是检验抗滑移系数的重要参数,按现行规范对高强度螺栓连接件滑移荷载判定的某些判据,受试验假象影响,得到的滑移荷载可能不准确。文中通过自行设计检验装置,对连接件滑移阶段的工作性能展开研究,研究结果表明:试验机回针不能反映滑移的整个工作性能,试件滑移先于试验机回针。因此,将部件间的滑移量作为判断滑移荷载更为合理。 Anti-slip load is an important parameter to test the anti-slip coefficient. According to the current standard, some criteria for judging the slip load of high-strength bolted joints may be imprecise because of the influence of test artifacts. In this paper, the self-designed testing device is used to study the working performance of the connector during the slip phase. The results show that the backlash of the test machine can not reflect the whole working performance of the slip, and the slip of the specimen precedes that of the test machine. Therefore, it is more reasonable to judge the slip load by the amount of slippage between components.
