Synopsis A Computer Analysis for Slender Reinforced Concrete Columns by J. Gaughan

A computerized finite difference method is presented for the analysis of slender reinforced concrete columns. The method is developed in detail for the particular case of columns fixed at the base and prevented from deflecting laterally at the top as compressive loading is applied. Symmetric bending is assumed. The columns may have a cross-section varying along the length. The effects of cracking of the concrete, initial lack of straightness, and of initial deflexion of the top of the column by cantilever action are allowed for. Reduction in the capacity of the column arising from creep of the concrete is examined. The method presented may be adapted to suit end conditions other than fixed base pinned top. Flow diagrams for the computer analysis are given.
