Shear transfer behavior at the circular tubed column-steel beam interface
Abstract This paper discusses the shear transfer behavior at the interface between circular tubed column and steel beam. Five beam-column connection specimens with crossing diaphragm were tested under monotonic loads, considering the key parameters of joint tube thickness, embedded diaphragm width, and crossing diaphragm thickness. Based on the experimental results, typical failure modes and load-displacement curves were obtained and discussed in details. A simplified finite element model was developed and validated with the experimental results. Parametric studies on the shear transfer capacity were carried out and analyzed. Lastly, practical formulas for estimating the shear transfer capacity are suggested.
Highlights A new connection between circular tubed column and steel beam is proposed. The shear transfer behavior is investigated by testing five connection specimens. A simplified finite element model is developed and validated. Practical formulas for estimating the shear transfer capacity are suggested.
