External Diaphragm Joints to Steel Beams
A large number of external diaphragm joints in CFST structures have been tested under a variety of conditions. For example, Wang et al. (2008) and Zhang et al. (2012) conducted a pilot study of eight external diaphragm joints under reciprocating loads; the other experiments conducted by Li et al. (2009), Quan et al. (2017), Shin et al. (2008), Wu et al. (2016), etc., showed that the external diaphragm joint was more feasible than other types of joints in CFST structures, and it could easily meet the design requirements of rigid joints. The current development of the external diaphragm joint in steel composite structure was also introduced by some researchers (Fadden et al. 2015; Vulcu et al. 2017; Sabbagh et al. 2013). The main contents were to (1) prove the feasibility of using an external diaphragm between a steel beam and a rectangular hollow section steel tube, (2) evaluate connection detailing requirements in hollow cross-section structures, (3) conduct parametric studies of the moment-resisting joints with external diaphragm collar plates using ABAQUS. To conclude, external diaphragm joints have relatively large stiffness, good plasticity, and high bearing capacity, so it could be applied in the CFDST structure. The external diaphragm joint is improved in terms of the cross-sectional feature of CFDST column in this book, and new test data pertaining to the mechanical behavior of the external diaphragm joint subjected to a cyclically increasing lateral load and a constant axial load was presented. Axial compression ratio of the CFDST column, width of the external diaphragm, configuration of the anchorage web and beam-to-column bending stiffness ratio are considered as the experimental parameters. Moreover, a new optical non-contact technique, digital speckle correlation method (DSCM), was used to measure and observe the joint in the low cycle reciprocating loading test. Further considerations were focused on the strain field in the panel zone and relative beam-to-column rotation, including the classification of joint stiffness.
