Abstract

Concrete filled stainless steel tubular (CFSST) columns have attracted increasing research interests in the last decade. This paper briefly introduces the material properties of stainless steel and reviews recent research on behaviour of CFSST columns and joints at both ambient and elevated temperatures. The reviewed studies include tests of bond behaviour between the stainless steel tube and core concrete, and the static behaviour of CFSST stub columns, slender columns, beams, stainless steel-concrete-carbon steel double-skin tubular columns, and concrete filled bimetallic tubular columns. The cyclic behaviour of CFSST beam-columns under combined axial and lateral cyclic loading as well as the impact behaviour of CFSST columns is also introduced. Fire test results of full-scale CFSST columns are presented along with finite element analysis results. The behaviour of composite joints with CFSST columns is also briefly reviewed in this paper. Based on the previous research, future research directions on CFSST are summarised and discussed.

Introduction

In the last few decades, the application of stainless steel in construction has attracted increasing interests among researchers and structural engineers. Compared with conventional carbon steel, stainless steel has several advantages, such as extremely high durability and corrosion resistance, easiness of maintenance and improved fire resistance. However, the high cost of stainless steel prevents its wide application as a structural material. To make more economical use of stainless steel, it is advisable to develop stainless steel-concrete composite structures. A good example is to fill stainless steel hollow sections with concrete to form concrete filled stainless steel tubes (CFSST). Fig. 1 shows typical cross-sections of circular and square CFSST columns, where D is the diameter of the circular steel tube, and B is the width of the square steel tube. In the past, extensive studies have been conducted on conventional concrete filled carbon steel columns and their behaviour has been well understood. Since the material behaviour of stainless steel is different from that of conventional carbon steel, some recent studies have been carried out to investigate the behaviour of CFSST members and joints. This is necessary to allow the development of any rational design guidelines for this type of innovative composite structure.
