主次梁螺栓连接中常规附加偏心距取值不合理,特别当次梁截面高度较小时节点的抗剪承载力偏低。采用有限元方法对梁与梁承压型螺栓单剪节点进行了非线性分析,提出改进的偏心距取值方法。
The value of conventional additional eccentricity in the connection of primary and secondary beam is unreasonable, especially when the height of secondary beam is small. The finite element method is used to analyze the single shearing point of beam and beam bearing bolts, and the improved eccentricity value method is proposed.
