Abstract

FRP has been generally acknowledged as a productive binding material for cement as a result of its high solidarity to-weight proportion and tailor-ability in mechanical properties. The concept of using various materials optimally in order to achieve a more efficient member is presented in this paper. Fibre-reinforced polymer (FRP) - Concrete- Steel double skin tubular (FCSDST) column is an advancement that emerged recently. It consists of outer FRP layer and inner steel pipe with concrete infilled between the tubes obtaining many advantages over existing columns in the vertical direction. This paper presents an analytical study on the behaviour of FRP concrete steel tubular column subjected to axial compression The stiffness and energy absorption capacity are determined. The analytical program includes testing of 12 specimens having height 500mm, varying parameters like thickness of 2mm & 4mm and diameter 160mm of the FRP tube and steel pipe of diameter 88.9mm of 1.6mm thickness. The analytical study has been carried out using Finite element software. Comparing with regular concrete GFRP attaining 25% more strength and prudent to other members.
