摘要:
采用有限元分析方法考察梁和柱的截面尺寸、角型连接件尺寸、铆钉直径及端距等对节点性能的影响，根据计算得到的弯矩-转角曲线拟合出三参数模型中形状系数n 值的近似计算公式。结果表明，柱翼缘厚度和角型件厚度对节点初始刚度和极限承载力影响显著，梁高和铆钉端距的影响次之。形状系数建议公式计算结果与试验结果吻合较好，可为该类连接节点设计方法提供理论依据。
Abstract:
The effects of beam and column section size, angle connector size, the diameter and end distance of bolt holes on the joints’ properties were investigated by finite element analysis method. According to the obtained moment-rotation curves, the approximate calculation formula for the value of the shape coefficient in the three-parameter power model was fitted. Results show the thickness of column flange and that of angle member have significant effects on the initial stiffness and ultimate bearing capacity of the joint, followed by beam height and end distance of bolt holes. The calculated results of the proposed shape coefficient formula are in good agreement with the experimental results, which provides a theoretical basis for the design method of this type of connection.
