Behavior of steel-reinforced composite concrete columns under combined axial and lateral cyclic loading

This study presents the experimental and numerical investigations on structural steel-reinforced concrete (SRC) columns under combined axial lateral cyclic loadings. The main parameters evaluated are peak strength, mode of failure, hysteretic response, stiffness degradation, energy dissipation potential SRC columns. A parametric has been conducted using a finite element software ABAQUS to predict flexural capacity varying load levels evaluate reliability design guidelines Eurocode 4 (2004) AISC 360-16 (2016) in predicting (P) - bending moment (M) interaction behavior In tension damage regions, data points mostly lie within or unfactored P-M envelopes both these standards. However, found fall outside compression region. For designed fail damage, provisions showed more reliable prediction failure loads uniaxial condition.
