Experimental And Finite Element Analysis Of Double Skin Circular Tubular
Experimental and Finite element Analysis of Double skin Concrete Filled tubes (DSCFT) are a variation of CFT
(Concrete- filled steel tubular) with a hollow core formed by two concentric steel tubes in – filled with concrete. Six Specimens
with three different volume fractions of steel fibers are cast and tested. Experiments on circular steel tubes in – filled
with steel fiber reinforced concrete (SFRC) and normal concrete have been performed to investigate the contribution of steel
fibers to the load bearing capacity of Short Composite Columns . The main Variable considered in the test study is the percentage
of steel fibers added to the in –filled concrete. All the specimens were tested under axial compression until failure
state realization. This project presents the percentage Variation in the compression strengths of the 3 types of Composite
members taken under Study. The results show that 1.5% SFRC in filled steel columns exhibit enhanced ultimate load carrying
capacity.Experiemental results compared and checked by the Finite element Analysis .
