摘要
针对节点实际存在刚度与理想计算假定刚度不一致的现象,推导了常见约束条件下半刚性节点转动刚度与节点弯矩关系的解析公式,并研究了节点转动刚度计算的解析法和实体有限元方法,以期促进对节点刚度的研究,提高工程设计水平。
Aiming at the phenomenon that the actual rigidity of joint is different from the calculating supposition, the paper deduces analytical formula of semi-rigid joint stiffness of the rotational and moment the relationship between nodes under common restrict condition. It analyzes analytic method of calculating semi-rigid joint stiffness of the rotational and finite method of entity. It aims to push analysis of joint rigidity and improve project design level.
