Development of a computer program to design concrete columns for biaxial moments and normal force

Design of a concrete column with biaxial moments and normal force is unpractical without the aid of a computer program. It is very time consuming to go through all calculations and to find a suitable layout of a cross-section and positioning of reinforcement for the final design. The goal of this thesis is to create a user friendly computer program for this problem. A critical pier in the Oland Bridge was used as a study case in this thesis.
