[提要]  报告了反复弯剪荷载下高强度螺栓摩擦面采用醇酸铁红处理的端板式连接节点的试验结果，并与单
向静力弯剪荷载下的连接性能进行比较分析。结果表明，对低抗滑移系数的高强度螺栓端板式连接，反复加载后的承载性能与单调加载时基本相同。

Test results of end plate joints with high-strength bolts connection and a certain rust inhibiting coatings under repeated moment and shear force are reported. The behaviors of the same joint under monotonic loads are compared. It is shown that for this kind of joint in the feature of low friction factors, their behaviors under repeated load are almost the same as those under monotonic loads.
Keywords: repeated load test; end plate connection; high-strength bolts; joint behavior
