| Abstract: | On the basis of the experiments carried out on axially compressed short columns, a numerical technique for simulating the collapse of concrete-filled square steel tubular columns under eccentric compression is presented. The Karman's formula for a column made of a single material is extended to the case with composite material. Numerical results show that the load-deflection (N-ym) curves obtained with the technique proposed are in good agreement with experimental ones. |
