Numerical study of concrete-filled austenitic stainless steel CHS stub columns with high-strength steel inner tubes

[EN] A numerical modelling programme simulating the structural behaviour of concrete-filled double skin tubular (CFDST) stub columns with stainless steel outer tubes and high strength steel inner tubes is presented in this paper. The numerical model, which was developed using the finite element pack...
