中文摘要
      进行了6组平齐式、外伸式端板单向螺栓连接节点试验,并在现有研究成果的基础上,分别推导了单向螺栓抗拉刚度、受拉端板抗弯刚度、柱壁抗拉刚度、柱壁抗压刚度和受压外伸式端板抗压刚度的计算式.利用组件法推导了平齐式、外伸式连接节点在弯矩作用下初始转动刚度的理论计算公式.结果表明:给出的节点初始转动刚度的计算式与试验结果吻合较好,精度可满足工程设计的要求.最后,提出了H型钢梁与矩形钢管(RHS)柱端板单向螺栓连接节点的设计建议.
英文摘要
      Tests of six groups of flushed and extended end plate connections using blind bolts were carried out. Based on the existing research results, the stiffness formulas of blind bolts in tension, end plate in bending, column wall in tension, column wall in compression and end plate in compression were derived. The theoretical calculation formula of the initial rotational stiffness of flushed and extended connections under bending moment was proposed by means of the component method. The results show that the calculation formula of the initial rotational stiffness of connections is in good agreement with the test results, and the precision can meet the requirements of engineering design. Finally, the design proposal of H shaped steel beams to rectangular hollow section(RHS) column end plate connections using blind bolts was put forward.
