Analytical Behavior of Rubber Concrete-Filled Steel Tubular Columns under Cyclic Loading
Keywords: concrete-filled steel tube; rubber concrete; analytical behavior; rubber replacing ratio; hysteretic behavior. Abstract: This paper presents a finite element analysis (FEA) model for the rubber concrete-filled steel tubular columns under cyclically increasing horizontal displacement loading. The cyclic load versus lateral displacement hysteresis curves was calculated by using FEA model to investigate the behavior of the columns. Based on the theoretical model, the influences of different column cross-section type (square, rectangular and circular) and rubber replacing ratio on the lateral load versus lateral displacement skeleton curves and rigidity degradation curves of rubber concrete-filled steel tubular columns were discussed.
