【摘要】 针对钢结构端板连接中高强度螺栓的应变松弛问题 ,对其预拉应变进行监测 ,根据试验结果 ,对高强度螺栓终拧后预拉应变随时间的变化规律进行了分析和对比 ,由此对钢结构端板连接中高强度螺栓施工中的扭矩检查提出了建议。更多还原

【Abstract】 In order to study the strain relaxation of high strength bolts in end-plate connections,the pretension strain has been monitored.Based on the tests results,the time-dependent rule of pretension strain of high strength bolts has been analyzed and compared,and proposals for the torque check of high strength bolts in end-plate connections after final screwing have been presented.更多还原
