STUDY ON CLASSIFICATION SYSTEM OF CONNECTIONS FOR 1 TO 4 STORIES STEEL FRAMES

摘要：

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, stiffness of column Ic and initial rotational stiffness Sj,ini· After calculating 729 models of steel frames, we get two formulas with the above seven parameters. One is the boundary between rigid and semirigid connections, and the other is 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.
