LRFD Software for Design and Actual Ultimate Capacity of Confined Rectangular Columns, Technical Summary
This study is intended to determine the actual capacity of confined reinforced concrete columns subjected to eccentric loading and to generate the failure envelope at three different levels. First, the well-known ultimate capacity analysis of unconfined concrete is developed as a benchmarking step. Secondly, the unconfined ultimate interaction diagram is scaled down based on the reduction factors of the AASHTO LRFD to the design interaction diagram. Finally, the actual confined concrete ultimate analysis is developed based on a new eccentricity model accounting for partial confinement effect under eccentric loading. The analyses are conducted for rectangular columns confined with conventional transverse steel. It is important to note that the present analysis procedure will be benchmarked against a wide range of experimental and analytical studies to establish its accuracy and reliability.
