BEHAVIOR OF FULLY ENCASED STEEL-CONCRETE COMPOSITE COLUMNS SUBJECTED TO MONOTONIC AND CYCLIC LOADING
Abstract
The paper presents a numerical model developed for fully encased steel-concrete composite columns under monotonic and cyclic loading. The numerical model was realized with the FineLg program, developed at ArGenCo department, University of Liège. The numerical model was validated using five experimental tests taken from the international literature: two realised at Technical University of Cluj-Napoca and the others in Taiwan, USA and China. The experimental tests used for validation of the numerical model dealt with both normal and high strength concrete. Different parameters were compared in the paper: partial and full ductility, energy dissipation, resistance and rigidity ratio.
