Behaviour of high strength concrete columns under eccentric loading
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.
