In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...

This study focuses on performance of H-shaped steel beams to CFT column rigid connections. To this end, the effects of internal and external stiffeners on hysteretic behavior of connections were studied. Comparative numerical analyses carried out on eight different connections. To this end finite element models were prepared using ANSYS and nonlinear cyclic analyses carried out. Results of this...

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that reinforced (RC) connection – CFT connections. The experimental program was carried out on five large-sized samples, including three UPC samples two RC samples. Steel plate details were utilised to increase bond betwee...

The paper discusses the structural behaviour of concrete-filled steel tube columns (CFT) when applied to top-down construction method as temporary internal supports for ceilings. Their ultimate capacity take into account actual boundary conditions column is essential successful application in construction. presents full-scale situ testing four slender specimens with variable D/t ratios under co...

Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...
