BEHAVIOR OF CONCRETE FILLED STAINLESS STEEL TUBULAR COLUMN UNDER AXIAL LOADS

Abstract

# $ % #& ! '( '( % core concrete. A CFSST column has gained prominence from structural engineers all over the world as it provides " % ) '( * + ( ' ( * $ ) ) $ % #& ! ) % % / ( $ ' '% various constructions. This paper presents a detailed experimental and numerical study on the compressive behavior of $ % ' %8 " ; ) % '( < ' ' * ( " " ( ( $ ' &= ) >?>G+ have been validated using the experimental data of the present study as well as recently published test results. The FE models predict the experimental load-deformation behavior, ultimate strength and failure modes with good accuracy. Once the FE model is validated, the numerical results are compared with the existing conventional carbon steel design code/guidelines and developed a prediction formula for CFSST columns.
