The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and shrinkage. The nature of their influence on the structure depends upon the type of linkage between the steel and composite columns. This paper describes the factors affecting the influence of creep and shrinkage on the structure and an approach to quantify their impact.
