“…Previous investigation on the experimental behavior of H-beam-to-CFST column connections has included that of Kang et al [1], Varma et al [2], Ricles et al [3], Shin et al [4], Cheng et al [5], Wu et al [6], Nie et al [7], Wang et al [8], Park et al [9], and Qin et al [10][11]. Theoretical study on the flexural strength and shear strength has been conducted by Kawano et al [12], Koester [13], Lu et al [14], Morino et al [15], Fukumoto et al [16], Park et al [17], Jiang et al [18], Nie et al [19], Rong et al [20], and Qin et al [21][22][23]. Additionally, various connection alternatives have been proposed and explored by researchers, such as the application of blind bolt [24][25][26], combined channel angle connections [27], and through-bolt connections [28].…”

This paper is an extension study to an experimental program involving one traditional and three novel through-diaphragm connections between concrete-filled rectangular tubular columns and steel H-beams. The proposed connection types utilize tapered diaphragm or triangular plates at the end of the beam to improve the seismic performance of traditional through-diaphragm connections. Based on the experimental results, the lateral force versus beam-column deformation response was assessed and the shear force versus shear distortion relationship in the panel zone was evaluated. It was observed that the improvement in connection details significantly enhanced the rotation capacity and shear stiffness. The deformation of the connections was also analyzed in terms of the contribution of the column, the beam, and the joint. In addition, the force transfer mechanism in the connections was investigated by analysis of the strain distribution The test results indicate that the proposed through-diaphragm connections are able to alleviate the stress concentration in the load transfer path and exhibit better seismic behavior. As a result, it can be concluded that the proposed connections are more suitable for applications in moment resisting frames in seismic regions.

Concrete-filled rectangular tubular column composite frame systems with steel beams have been widely used in moment-resisting frames for engineering practice. This paper reviewed a variety of connection details to concrete-filled rectangular tubular (CFRT) columns that have been developed by different researchers. The research on CFRT connections was divided into three phrases. The first phase dates back to the late sixties of twentieth century, when the steel moment-resisting frames were regarded as one of the most ductile systems. The second phase is defined as the period between middle nineties and the beginning of the twenty-first century, during the early stage of which the Northridge earthquake and Kobe earthquake occurred and the conventional knowledge of traditional connections were subverted, leading to the requirement of paying more attention to the investigation of connection behavior under seismic loading. The third phase passes through the following year up to the present. During this phase, various connection alternatives were proposed and studied. Based on the summary of previous studies, the future developments were presented at the end of the paper.

“…An inelastic rotational spring combined with fixed-end multi-point constraint was used to simulate the shear-deformation relationship of the panel zone. The nonlinear shear-deformation model developed by Fukumoto and Morita [21] for panel zones was adopted in the model. The rotational springs at the end of beam were used to model the nonlinearity of bolted endplate.…”
