【摘要】 根据H型钢梁柱外伸端板螺栓连接节点的简化力学模型，提出用节点尺寸来计算节点初始转动刚度Ri的计算公式，通过与试验结果比较，验证了初始转动刚度Ri的计算公式的正确性；并对节点的破坏形式、抗震性能及影响节点初始转动刚度的因素进行了分析讨论。更多还原

【Abstract】 Based on the simple mechanical model of H-steel beam-to-column extended-end-plate bolted connections, a formula was proposed to calculate the initial rotational stiffness by use of the known sizes of the connections in this paper. Compared with the test results, the formula is testified . The failure mode, the earthquake-resistant behavior and the influencing factors on the initial rotational stiffness are also discussed at the end of this paper.更多还原
