Analytical Study on Seismic Performance of Self-Compacting Concrete Column Reinforced with Steel and GFRP Rebar

Abstract

The self-compacting concrete is described as one of the environment friendly concrete which has several benefits over ordinary concrete. The main advantages of self-compacting concrete are that problem associated with vibration is eliminated. It is a non-segregating concrete that have benefits such as high bond to reinforcing steel, superior strength and durability, improved structural integrity etc. The Glass Fiber reinforced Polymer (GFRP) rebars are preferable alternative to steel rebars for minimizing corrosion problems In this paper, analytical study is carried out to investigate the seismic performance of self-compacting concrete circular columns reinforced with GFRP rebars and are compared with columns reinforced with steel rebars. The main parameters considered for the study are slenderness ratio and confinement techniques. The circular column of slenderness ratio 4, 6, and 8 are considered for the study. The seismic performance is carried out by Push over analysis using ANSYS software.
