Abstract

The calculation of reinforcement ratio of concrete columns is very significant since the calculation will guarantee the columns ductility and reinforced efficiency. However, this calculation spent a lot of time and accuracy. Hence the manual calculation will not be efficient. On the other hand, a lot of computational programs are developed recently for civil engineering calculations. This study presents a useful computer-aided program that can be used to calculate the required longitudinal reinforcement ratio in a circular column. The code of this developed program adopts from SNI 30-2847-2002, which the reduction factors based on governed by the axial load in column capacity. As comparison the developed program also adopts ACI 318-2002, which the tensile strain that controls the reduction factor. The results from this program will be verified with PCA Column for output validity.
