This paper presents a study of the behaviour and design of concrete fi
lled high strength steel fabricated box columns for use in tall buildi
ngs. The many advantages that can be attributed to the use of high str
ength steel in concrete filled steel box column constructions are pres
ented and discussed. The paper deals with short composite columns and
presents guidelines for plate slenderness and overall column slenderne
ss to eliminate local and overall buckling. A proposed design model is
developed to calculate the strength of short columns in bending and c
ompression. A method for constructing the strength interaction diagram
is presented. Furthermore, to study the ductility of this form of col
umn construction a cross-sectional analysis computer program was devel
oped to consider the moment-thrust-curvature response of such members.
This has been undertaken using mild structural steel and high strengt
h steel. The study also shows that, by the use of the method considere
d, savings can be made in the base column design of a tall building wi
th a negligible penalty in ductility. Finally, recommendations are giv
en for further research into this new method of column construction, w
hich focuses on future experimental work.
