Behaviour of confined high strength concrete column subjected to concentric and eccentric loads

In common practice, columns are subjected to a combination of an axial load and a bending moment in different direction. The only axially loaded columns are rarely occurred. However, most of the studies have concentrated on column which subjected to concentric load rather than eccentric load. In thi...
