Behavior of circular tubed-RC column to RC beam

The circular tubed-reinforced concrete (TRC) column is a kind of special concrete-filled steel tube (CFST) columns, in which the outer thin-walled steel tube does not pass through the beam-column joint and thus can avoid the direct transfer of an axial load and maximize the confinement effect from the steel tube.

Shear behavior of large-diameter concrete filled tube (CFT

Dec 31, 2017 · Circular concrete filled tube (CFT) is composite structure to fill concrete in steel tube as formwork. By combining advantage of steel tube and concrete, CFT has more superior deformation capacity and strength than reinforced concrete and steel structure, since bond stress between steel tube and concrete has influence on prevention of local buckling and increase in strength of concrete.

stub columns under compression are shown in Figure 3. It can be seen that the core concrete of circular columns has good integrity. However, for square columns, core concrete is crushed at the buckling positions of the stainless steel tube. It also confirms the previous observations that the RACFST stub columns containing

Analytical Behavior of Rubber Concrete-Filled Steel

Keywords: concrete-filled steel tube; rubber concrete; analytical behavior; rubber replacing ratio; hysteretic behavior. Abstract: This paper presents a finite element analysis (FEA) model for the rubber concrete-filled steel tubular columns under cyclically increasing horizontal displacement loading. The cyclic load versus lateral displacement hysteresis curves was calculated by using FEA ...

Behaviour of circular concrete-filled lean duplex stainless

Nov 01, 2013 · In the early stages of loading, the Poisson’s ratio of the concrete core in a circular CFST column is less than that of the steel so that the steel tube does not provide confinement on the concrete core as discussed by Neogi et al. and Johansson and Gylltoft . As the loading increases, the Poisson’s ratio of concrete increases and becomes greater than that of the steel tube.
