TLDR
In this article, a finite element analysis (FEA) of concrete-filled thin-walled steel tubes subjected to pure torsion is used to investigate the influence of important parameters that determine the ultimate torsional strength.Abstract:
In practice, concrete-filled steel tubes (CFST) are often subjected to torsion. To date, such a problem however has not been addressed satisfactorily by design codes. The present study is thus an attempt to study the torsional behaviours of concrete-filled thin-walled steel tubes. ABAQUS software is used in this paper for the finite element analysis (FEA) of CFST subjected to pure torsion. A comparison of results calculated using this modelling shows good agreement with test results. The FEA modelling was used to investigate the influence of important parameters that determine the ultimate torsional strength of the composite sections. The parametric studies provide information for the development of formulae to calculate the ultimate torsional strength, as well as the torsional moment versus torsional strain curves of the composite sections.read more

Finite element modelling of concrete-filled steel stub columns under axial compression
TL;DR: In this article, a finite element (FE) model for CFST stub columns under axial compression is presented. But the model is not suitable to be used in some cases, especially when considering the fast development and utilisation of high-strength concrete and/or thin-walled steel tubes in recent times.

Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.
