摘要
针对钢结构工程的高强度螺栓摩擦型连接中,已经出现采用大圆孔或槽型孔的情况,对不同螺栓孔径与孔型的高强度螺栓进行预拉力损失试验和抗滑移试验,以研究分析预拉力以及抗滑移系数随着孔径、孔型变化的规律。
The frictional joints of high strength bolts with oversized holes or slotted holes have been used in domestic construction. The tests of prestressing loss and antislip of high strength bolts with different diameter or hole type of bolt hole have been done. Based on the results, the diameter or hole type depended rule of prestressing of high strength bolts and antislip coefficient have been researched and analyzed, and proposals on design of high strength bolt frictional joints with oversized or slotted hole have been presented.
