摘要
介绍了一些现有的梁柱节点分类标准,并通过参数分析的方法提出了一个新的多层钢框架结构的节点刚度分类标准.参数包括层数m,跨数n,层高H,跨度L,梁刚度Ib,柱刚度Ic.在计算了288个模型之后,得到了两个包含以上6个参数的表达式.其中一个表示了刚接和半刚接的分界,另一个表示了铰接和半刚接的分界.通过对几个多层钢框架结构静力性能的分析,这一分类标准的有效性得到了证明.与现有的分类标准相比,提供了一个更为合理的分类标准.
It is important to propose a valid classification system for multistory steel frames. In this paper, some existing familiar classification systems for beam-to-column connections are presented. And a new classification system is established by parameter analysis. The parameters include the number of stories m, the number of spans n, story height H, span L, stiffness of beam Ib and stiffness of column Ic. After having calculated 288 models of steel frames, we get two formulas with the above seven parameters, one being the boundary between rigid and semirigid connections, and the other the boundary between pinned and semirigid. The validity of the proposed classification system is examined by analyzing the overall behavior of multistory steel frames. As a result, it is confirmed that the new classification criteria provides a more rational boundary compared with the existing classification system.
