“…A square hole is in the middle of the endplate to allow the shear key to pass through, which is somehow similar to the connection described in Figure 2(c) [12]. Better structural performance can be assumed if circular hollow section for the shear key is adopted and then the hole in the endplate is adjusted to circular [34].…”

“…The analysis from this theoretical simulation included the models of 2-sample of the RCFT, which was built-up in ABAQUS 6.13 -4 (Figure 4) [14,43,44] to figure the behaviour of RCFT on the carrying capacity with and without reduce beam section (RBS) is conducted. The analysis was carried out on the hollow-rectangular cross section using 500×500×20 mm 3 (steel grade 41 according to Indonesian standard) [45][46][47][48] with the attached welded plate PL 16.95.470 mm.…”

“…The different of those 2 measuring results is the used of inclinometers that handle the angle of the rotation of the joint. This measuring can also be evaluated by potentiometers or linear variable differential transformers which is installed between the column and the beam end [7,14,15]. Previous study was conducting various experimental investigation performing the physical and mechanical performances of beam with concrete filled tube (CFT) column connections.…”

Recent condition of the earthquakes model has shown that rectangular concrete-filled tubes (RCFT) with weld connection are so brittle. According to the studies conducted, large damages are due to the cracking of the weld between the beam flange and the column face and inducing concentrated stresses in this area. One of the novel alternatives to reduce the stress concentration at the panel zone could be the use of the reduce beam section (RBS). Given the enormous impact of seismic behaviour and ductility of the panel zone, RBS moves plastic hinges formation at an appropriate distance from column face. In this study, 2 major model of RCFT with and without RBS have been modeled using ABAQUS computer program and compared under cyclic behaviour. The obtained result of this study showed that using RBS is more ductile and implied a good stability. It also will consider having better ductility than other connections. GRAPHICAL ABSTRACT

“…Some scholars at home and abroad have carried out a lot of experimental researches and finite element numerical simulation the connection of square steel column and H-shaped steel beam with the blind bolt [3][4], which indicated that the connections have a good hysteretic property but low bearing capacities. Through the experiment and the finite element simulation research, doung et al [5] found that setting the internal diaphragm in the square steel column can effectively improve the connection performance of the beam-column joint. Cao et al [6] developed a new type of outer sleeve assembly between steel beam and square steel column, which has good energy dissipation and ductility through the numerical analysis.…”

"A kind of assembled steel beam-column joint with C-shaped cantilever section was proposed. The influences of the lengths of cantilever sections and cover plates on seismic performance of the joints were discussed through low-cycle reciprocating loading tests and numerical simulations. Then the sensitivity analysis of key parameters such as thickness and width of flange plate ,bolt number and cover plate’s length were carried out. The results show that the joint consumed energy through warping deformations of end plate and the friction slippages between flange of beam, C-shaped cantilever section and cover plate. By reasonably increasing the lengths of C-shaped cantilevers section and cover plates, it can ensure that the joints have high bearing capacities, while significantly improving energy dissipation capacities of the joints. Parameter analysis showed that increasing thickness of the flange plate can effectively improve the stress concentration at root of the cantilever section. Reducing width of flange plate has a great impact on bearing capacity and initial stiffness of the joint with the maximum drop amplitude of 13.1% and 18.9%, respectively."
