Abstract

In this research the behavior of frame with concrete-confined steel composite column is studied. In turn, three dimensional (3D) finite element nonlinear model is used for analysis of inelastic behavior of concrete, steel, longitudinal reinforcements, transverse reinforcements and also the effect of concrete confinement for concrete- confined steel composite columns and the modeling procedure is performed by ABAQUS software. Three types of frame composed of concrete-confined steel composite columns with SRC beam, steel section beam, and reinforced concrete beam are modeled and the effects of parameters of compressive strengths of concrete and yield tension of steel section on the frame behavior and strength are studied for each one of these three frames. The results show that increasing these two parameters improves and increases the behavior of frame and its strength. The effect of increasing compressive strengths of concrete for SRC beam frame and also the effect of increasing yield tension of steel section is more pronounced for steel section frame, while increasing both parameters for reinforced concrete beam frame has almost identical effect on increasing and improving the frame behavior.
