DEVELOPMENT OF CONNECTIONS TO CONCRETE-FILLED

409 Development of Connections to Concrete-Filled Rectngular Tubular Columns The CFRT column-to-beam connections are broadly classified into two categories [4]. The most convenient way is directly attaching the steel beam to the column tube or through the diaphragm plate. For the other connection category, the beam flange, the web or the entire ...

Such connections represent a simple single-sided joint solution to steel CFTs. The current design method for similar connections under purely tensile load, in CIDECT Guide 9, based on a deformation limit of 0.03 of the tube width is shown to be inadequate when evaluating the ultimate strength of such connections.

BLIND-BOLTED MOMENT RESISTING CONNECTIONS TO

Despite the merits of concrete-filled steel tubes, connecting a steel I-beam to a circular hollow section column using conventional bolts is difficult due to lack of access to the inside of a hollow section. To avoid welded connections, the blind-bolted connections are designed to be easy to install to facilitate quick erection of the frames.

Thereby, the work of the beam web near the connection is strengthened due to the presence of the additional shear plates. Therefore, α = M FE, c /M p, b would be sometimes greater than 1.0, as shown in Fig. 16.
