【摘要】 本文介绍了欧洲规范EC3中关于高强螺栓受拉连接等效T形件的三种破坏模式及等效受拉T形件三种破坏模式下的承载力公式。研究了柱翼缘带有背板加强的T形件的承载力公式,通过与无背板加强T形件的承载力比较得出:柱翼缘受拉螺栓孔位置设置背板能够有效地提高T形件翼缘的抗拉承载力,增大柱翼缘的抗弯能力。最后,研究了端板塑性铰线分布模式以及等效T形件有效长度的取值方法。更多还原

【Abstract】 The three failure modes and the resistance equation in the three failure modes of an equivalent T-stub in tension for high-strength bolted connections in Eurocode 3 is introduced.The capacity of the T-stub connecting to column flange with backing-plates is researched.By comparing the capacity of the T-stub without backing-plates,we can get the conclusion that the use of backing-plates can increase the tension capacity of the T-stub and the bending capacity of the column flange effectively.Finally,distribution patterns of plastic hinged lines of the end plate and the effective length of an equivalent T-stub flange is reseached.更多还原
