Simulation Flexural response of concrete-filled seamless steel tubes in Abaqus

This tutorial aims to investigate the flexural behavior of concrete filled tubes (CFST)made of seamless steel.Finite Element Analyses are utilized for this purpose.Concrete-filled steel tubes (CFSTs) are composite structural mem-bers constituting of a steel tube and a concrete infill. Both materials mutually contribute to carrying the load and providing the necessary member stiffness where the steel tube improves the carrying capacity of the concrete and the concrete core delays the global and local buck-ling of the steel tube.In current construction practice, CFSTs are commonly used as columns and braces in tall buildings, bridges and military facilities due to their large axial load capacity, compression stiffness and high deformation capacity.You can see a experiment picture at below

A nonlinear finite element model capable of simulating the flexural behavior of CFST specimens was developed using the commercial software ABAQUS Material and geometric non linearity were considered in the developed FE model.Linear four-node three dimensional (3D) solid elements with re-duced integration (C3D8R ABAQUS type) were used to model the concrete infill and the steel tube to simulate the flexural capacity of CFST specimen.Static general step analysis is appropriate for this type of analysis. You cans see some results of this simulation at below
