Abstract

With the increase in the strength of concrete, the ultimate strength of concrete columns shows the high load carrying capacities under axial compression. However, in general, a concrete shows low tensile strength coupled with high compressive strength. Therefore, a concrete column sometimes exhibits a brittle failure. Also, a column is subjected to an eccentric loading due to structural arrangements. In this case, the column is under combined bending and compression. To obtain a high ultimate strength and a ductile behavior of a concrete column under such loading conditions, it is important for concrete to resist both an axial load and an additional flexural compressive load. Such a problem plays an important role in the realisation of light weight and the economical structures.
