    摘要:

    对32组Q690高强钢高强螺栓(10.9级或12.9级)抗剪连接进行试验,观察到连接钢板的剪出破坏、撕裂破坏、承压破坏、净截面破坏和螺栓剪切破坏共5种破坏模式。通过分析试验数据,发现Q690高强钢有良好的局部变形能力,研究了螺栓等级、规格、预拉力和端距、边距对试件承载力和变形的影响。收集了多篇文献中的试验数据,得到剪出破坏、撕裂破坏的几何界限约为(0.7~0.9)e1/e2,净截面破坏试件的应力比均大于1.0。

    Abstract:

    Bearing-type shear connection of 32 sets of Q690 steel-highstrength bolts (property grade 10.9 or 12.9) were studied through experiments. Tear-out failure, splitting failure, bearing failure, net cross section failure, and bolt shear failure were observed. Through the analysis of the test data, it is found that Q690 highstrength steel had good local deformation ability. Furthermore, the effects of bolt grade, size, pretension, end distance, and edge distance on the bearing capacity and deformation of the specimen were studied. The experimental data in several papers were collected and analyzed, showing that the geometric limit between the tear-out failure and splitting failure was about from 0.7e1/e2 to 0.9e1/e2, and the stress ratio of the net section failure specimen was greater than 1.0.
