The Effect of Lateral Reinforcement in Reinforced Concrete Columns

Whilst it has been accepted since the days of Considere's work at the beginning of the century, that a helical form of lateral reinforcement increased the strength of a reinforced concrete column, so far as the Author is aware, it has never been claimed that the ordinary hoop form of binder gives any material contribution to the ultimate strength of the column. This Paper, amongst other points, submits the results of tests to destruction of nearly 200 small columns, and indicates quite definitely that the normal binders, if placed at a sufficiently small pitch, can contribute considerably to the load carrying capacity. It also questions the currently accepted practice of ascribing the helical binder effect to its function in restraining the lateral expansion of the concrete. Jeffrey William Hitchen King
