Abstract

Clause 5.8.3.1. of the Eurocode 2 (EC2) recommends a slenderness limit (λlim) for compressive members where second order effects can be ignored. This equation shall be used to study the effects of lateral reinforcements in the compressive member. The effects of spiral-shaped steel confinements on the reinforced concrete columns of 9 numbers of 125mm×125mm×500mm reinforced concrete columns, all exceeding λlim were investigated with one control column i.e. without any reinforcements, another four were confined with single spiral of 50mm pitch and the last four were confined with double spiral of 100mm pitch. This result in having the same volume of confinements introduced for all the confined concrete columns. The confinement used for the concrete were mild steel rebars of 6mm diameter. It was found that with the introduction of spiral-shaped steel confinements, the ultimate failure load of these columns exceeded the control sample and hence there is a possibility of increasing the λlim factor of EC2 by considering concrete confinements.
