摘　　要：为了开发无主檩螺栓球节点网架结构,设计了新型抗剪性螺栓球节点,通过压、拉、剪试验,对M24、M27、M30三种不同螺栓直径的新型螺栓球节点进行试验,研究其各组成部件及整体力学性能。结果表明:节点受压时,新型节点套筒比普通节点的更抗压,且新型节点螺栓承受了一定的力;受拉时,两种节点各部件力学变化规律一致;受弯剪时,新型节点抗剪性能有一定提升,M24、M27、M30新型节点的极限弯矩分别提升了2%、6%、13%。将试验结果和模拟结果进行对比,最大误差不超过10%左右。In order to develop the grid structure of the ownerless purlin bolt ball joint,a new shear bolt ball joint was designed,and the ball joints of three new bolts with different bolt diameters of M24,M27 and M30 were tested through the compression,tension and shear tests,and their components and overall mechanical properties were studied.The results show that when the joint is compressed,the new node sleeve is more compressive than the ordinary joint,and the new node bolt bears a certain force.When tensioned,the mechanical variation law of each component of the two joints is consistent.When subjected to bending shear,the shear resistance of the new joint is improved to a certain extent,the ultimate bending moments of the new M24,M27 and M30 joints are increased by 2%,6%and 13%respectively.The test results are compared with the simulation results,and the maximum error is not more than about 10%.
