In this tutorial Simulation, inclined concrete-filled steel tube column (CFST) under axial load in Abaqus has been studied.The concrete core is modeled as three three-dimensional solid parts, the steel tube as a shell part, and the rigid plate as discrete rigid. You can see a figure of the assembled part
The application of concrete-filled steel tubular (CFST) columns in construction has been in use for more than 40 years. It has been recognized that concrete-filled steel tubular composite columns utilize the most favorable properties of both constituent materials and the interaction between the steel hollow section and concrete core makes the composite column perform better structurally than individual constituent members but without significant increases in cost. To meet the architectural, aesthetic, and constructional requirements in modern constructions, inclined, tapered and straight–tapered–straight (STS) members have been used in long-span structures, viaduct piers, and high-rise buildings
To model concrete behavior CDP or Concrete Damage Plasticity and to model steel elastic plastic behavior with ductile damage criterion are used.
This simulation is done by two ways,the first dynamic explicit method and the second general static and at the end the result are compared from two simulations. Perfect contact is assumed between the steel and concrete parts. The general contact algorithm with friction behavior is implanted. The proper boundary conditions is assigned to the rigid bodies. The mesh size needs to be the same for concrete and steel tube
After the simulations, all results such as stress, strain, damage, and force-displacement diagram can be available. You can see some figures of the results below
