Abstract:
A method to calculate the strength of reinforced concrete slender columns in braced frames is presented. It is based on a simplified stability analysis of a standard pin-ended column. The method includes the creep deflection due to sustained loads as an additional eccentricity. The strengths calculated by the proposed method show good correlation with 80 test results reported in the literature. When compared with the proposed method, the slender-column provisions contained in the ACI Building Code are found to be conservative. Based on the method, proposals for design are made and illustrated by an example.
