“…Results indicated that stronger and stiffer moment-resisting connections were obtained. Benefits of the blind-bolt extensions anchored within concrete were also confirmed with the experimental investigations of Wang and Chen [15], but for the case of complete extended end plate connections to CFT.…”

“…Installation procedure for Ajax ONESIDE [13] Furthermore, the effect of extending the shank to achieve stronger and stiffer moment-resisting connections to concrete filled columns was investigated by Yao et al [14], who welded a curved and threated extension at the end of the bolts. Wang and Chen [15] worked also on this anchorage extensions proving their benefits. The anchor within concrete permits a better stress distribution, so less stress concentrates on the column face.…”

“…However, the study object was mainly traditional welded steel tubular joints. Wang et al [5] conducted a monotonic loading experiment to study the behavior of extended end-plate joints of circular or square concrete-filled steel tubular (CFST) columns. Results showed that joints exhibited high strength and stiffness, while its rotation ability satisfied the demand of seismic ductility.…”

A considerable amount of welding has a negative effect on traditional joints. Experimental and numerical studies of new bolted outer shell joints under low reversed cyclic loading were presented, and a total of four outer shell joints of Hshaped steel beam and square tubular column were tested with experimental parameters, such as sectional dimensions and concrete in the tubular column, to improve the beam-to-column joint form. Moreover, the cooperative deformation behavior between the outer shell and the column wall was discussed. In addition, complementary finite element simulation was used, and its results were compared with the experimental results. On this basis, the main indexes that affected the performance of the joints were analyzed. Results show that the hysteresis curves of the outer shell joints are full, the bearing capacity and initial stiffness are significantly improved with the increase in the sectional dimensions, while the ultimate rotation angles are reduced, degrading the stiffness to 0.13-0.24 times its initial stiffness at the last loading level. Notably, the strain ratios of the outer shell and the adjacent steel tubular column are approximately 1:2.5 in the elastic stage. Parametric analysis shows that the thickness of the outer shell should be approximately 8 mm. Similarly, the 11 mm thick T-steel web with regard to the setting stiffener is significant in improving bearing capacity. The proposed study provides a theoretical reference for the application of outer shell joints in practical engineering.

“…In recent years, few experimental and numerical studies have been carried out to investigate performance of the CFST column to steel beam moment connections with curved and-plates [1]- [3], which were then adopted for the composite beam to stainless and carbon steel concrete filled columns [4], [5]. In summary, researchers emphasized on the superior performance of the circular CFST connections and did not consider the prying action.…”

Parametric Study of the Curved T‐stub in Tension

This paper presents parametric study of the T‐stubs with curved end‐plates in tension. Influence of the key parameters such as curvature, bolt arrangement and the thickness of the end‐plate on the strength and stiffness of the T‐stub is investigated. In curved T‐stubs bolts not only undergo tension, but are also subjected to shear, which limits the use of the conventional prying models. Apart shear, due to curvature, determination of the total effective length of a T‐stub is not trivial, and the collapse mechanisms of the end‐plate are uncertain. To clarify behaviour of the curved T‐stub and to determine the influence of the curvature on prying and shear, FEM results of 108 T‐stubs were analysed.
