摘要:

对欧洲规范Eurocode 3的组件法进行改进,考虑了带加劲肋的外伸端板与柱翼缘之间的拉伸刚度组件,使之可用于计算门式刚架结构中最常见的设置了加劲肋外伸端板连接节点的初始转动刚度,同时给出了该类节点的初始转动刚度的简化分析模型以及详细计算步骤,并通过试验进行了验证。结果表明:所提出的方法计算结果与试验结果吻合较好,可用于目前部分不符合规范刚性连接要求的门式刚架节点的初始转动刚度的确定,并为该类结构整体承载力的分析计算提供依据。

Abstract:

A modified component method introduced in Eurocode 3 was presented. The component of tensile stiffness between stiffened extended endplate and stiffened column flange was considered. The calculation of initial rotational stiffness for stiffened extended endplate connection that was most common in portal frames would be possible by this method. The simplified analytical models and calculation procedures for such kind of joint were provided in detail. Experiments were carried out to verify the method. The results show that the presented method basically coincides with the experimental results. The method can be utilized to determine the initial rotational stiffness for part of the existing joints of portal frames that does not correspond with the requirements of rigid presupposition. The determination of joint initial rotational stiffness is also the precondition of force analysis for such kind of structure.
