The article “Hysteresis Behaviour of CFT Column to H-Beam Connections with External T-Stiffeners and Penetrated Elements” (C. Kang, K. Shin, et al., Engineering Structures, 2001:1194–1201) reported the results of cyclic loading tests on concretefilled tubular (CFT) column to H-beam welded connections. Several test specimens were loaded until failure. Some failures occurred at the welded joint; others occurred through buckling in the beam itself. For each specimen, the location of the failure was recorded, along with the torque applied at failure [in kilonewton-meters (ken · m)]. The results for the first five specimens were as follows:
Which data are numerical, and which data are categorical?
