摘　　要：针对现行规范中高强度螺栓承压型连接不应用于直接承受动力荷载结构的规定,引出关于动力荷载的讨论,进而讨论承压型连接高强螺栓的适用范围,比较了各种规范对于高强度螺栓连接的规定,明确其基本要求之一是弹性阶段连接不能滑移,据此要求,对高强度螺栓承压型连接未滑移时和已滑移时的承载力与摩擦型连接承载力进行比较,最后总结了高强度螺栓承压型连接的各种适用范围。The high-strength bolted bearing-type joints should not be used for the structure carrying directly dynamic loads according to the current codes, which leads to the discussion on dynamic loadings, and then the applicable range of the high-strength bolted bearing-type joints is also discussed, to clarify one of the basic requirements of the joints in elastic stage is that the joint cannot slip, according to this requirement, the bearing capacity of high-strength bolted bearing-type joints with and without slip and that of the frictional joints are compared, finally it is summarized all kinds of the application scopes of the high-strength bolted bearing-type joints.
