【摘要】 高强栓接梁柱连接通常可以被简化为T形连接件,总结国内外规范和文献,归纳螺栓附加力的研究现状。在拉力荷载作用下,由翼缘板变形所产生的附加力,会增大螺栓内力,导致连接失效破坏。附加力包含撬力和弯矩,翼缘板厚度、宽度、肢长、栓孔位置、垫板以及翼缘板倒圆角和螺栓直径都对撬力大小有影响。国内外研究以撬力为主,通常忽略了螺栓弯矩。在实际负荷中,螺栓处于拉弯状态,螺栓所受到的弯矩不应被忽略。更多还原

【Abstract】 The high strength bolted beam-column connection can be simplified to T-shape,and this paper summarizes the domestic and foreign standards and literature to summarize the research of bolt additional force.When tensioned,the additional force caused by the deformation of endplate will increase the stress of bolt,causing the failure of connection.Many factors affect the prying force,such as flange plate thickness,width,length,the location of bolt hole,diameter of bolt and fillet of flange.The additional force include prying force and moment,however,the research allover world mainly focus on the prying force.On actual loading,the bolt is in tension and bending state,and the moment of bolt should not be ignored.更多还原
