Modelling of steel-concrete composite joints

Experimental behaviour of end-plate beam-to-column composite joints under monotonical loading

“…Based on the works of Zandonini [4] and Choo [20] and on the results of the experiments described above and similar results from the tests held by Bernuzzi et al [21], Tschemmernegg [22], Badran [23], Ren [24], Shanmugam [25] and Wong et al [26] it can be concluded that:…”

“…The lighter the steel joint, the bigger the effect [24]. Fairly stiff joints can be achieved using quite simple steel joints, reaching hogging moments of the same order of magnitude as the composite section [7][8][9][10]25]. ț Resistance and stiffness increase with increasing slab reinforcement [12,13].…”

“…According to Elnashai [27], effective anchorage is achieved whenever at least 40% of the longitudinal reinforcement circumscribes the column. ț The use of columns embedded in concrete has a significant effect in the behaviour of the joints, the concrete covering the web of the column contributing to the behaviour of the column, similarly to stiffeners [25]. ț In the case of slabs with metal decking, the direction of the corrugations influences the behaviour of the joint.…”

Shear Storage Capacity of Vertical Stiffener Joints between Concrete-Filled Double Steel Tubular Columns and Steel Beams

“…According to the principle of structure design "strong shear and weak bending," shear strength becomes the control condition of the strength calculation. When shear strength calculation was not estimated accurately, the structure would lead to the lack of shear capacity even the shear failure [19][20][21][22][23], so shear storage capacity was analyzed in this paper based on the low cyclic loading test results of vertical stiffener joints between CFDST columns and steel beams. A conceptual model is presented for assessing the cracked vertical stiffener joints with shear failure.…”
