Abstract

Concrete filled steel tube (CFST) and steel castellated beam are ideal components in the structure. However the research about the connection of them is less at present. In order to analyze the working mechanism of outer annular-stiffener type steel castellated beam-concrete filled steel tube (OATSCB-CFST) joint, load-bearing process of this type of middle column joints under low cycle load are simulated by finite element software. Before simulating, the simulation method is verified by the test data of a middle joint of outer annular-stiffener type steel solid beam-concrete filled steel tube (OATSB-CFST). The results show that: the high stress area of the OATSCB-CFST joint is mainly focused on the position of the castellated beam and the annular-stiffener near the border between them, the position of the tube near annular-stiffener, the position of the annular-stiffener near medial axis of the steel beam, and the position of the core zone concrete. This implies that the annular-stiffener zone should be a key consideration in the design.
