Experimental Study on High Performance Concrete Filled Tubular Short Columns

Abstract

Concrete filled steel tube structural system is based on filling steel tubes with concrete. The CFST structural system promots excellent structural characteristics, like strength, deformation capacity, and fire resistance for use in many fields of construction. Composite columns composed of concrete filled steel tubes have become increasingly popular in structural applications around the world. This type of columns can offer many advantages like high strength, ductility and large energy absorption capacity with possible use of simple standardized connections. The main aim of my project is to manufacture the normal M20 mix and nano silica CFST, steel fibre CFST and geo polymer concrete filled steel tubular columns under compression.
